2nd June 1990, Earth, Present Day.

Linus woke up early, so he figured he could finish reading the book before having his breakfast. The book held detailed notes on races such as the Daleks and the Cybermen, and of the ways The Doctor had used his sonic screwdriver to help him on his adventures. With the book finished, he went downstairs to have breakfast, before getting himself dressed, and brushing his teeth. He walked out of the house, wearing his blanket as a scarf and with his sonic screwdriver zipped up in his right pocket.

Sally, in a burst of creativity, had decided today to be, or at least imagined herself to be, Ace Detective Sally Brown, the world famous private investigator. Wearing a light brown longcoat over her usual clothes, she went outside and proceeded to make herself an office, grabbing a desk and a chair, dropping the desk right next to Lucy's psychiatry stand. Sally set up her chair and sat down. When Lucy arrived at her psychiatry stand, less than 5 minutes later, she was not best pleased.

"What are you doing next to my psychiatry stand, Sally?!" she shouted "Are you trying to take customers away from me?!"

"I'm a private investigator!" Sally replied, clearly, at a volume that, whilst loud, didn't show anger. "Do you have a mystery for me to solve?" she asked Lucy.

"Well," began Lucy in a playful manner "I'd like you to investigate the possible sighting of an alien during the daylight hours of yesterday."

"An Alien?" Sally responded "This seems like an important case. I'll give you any info if I find out anything about this alien." She said as she got up from her seat and brandished her magnifying glass at nowhere in particular.

Lucy began to violently dismantle Sally's office as soon as she was out of earshot. Sally, however, was searching for clues about the mysterious alien. The first person to ask, she thought, would be Linus. But then she figured it would be easier to ask her brother first, since she knew where he would be. Sally went back inside her house. Charlie Brown was sitting in the living room, watching Saturday morning cartoons.

"Big brother, may I ask a few questions?" Sally asked. Charlie Brown looked in her direction.

"I don't see why not" Charlie Brown replied.

"Well, Lucy has asked me to investigate the possible sightings of an alien during the daylight hours of yesterday. Do you have any information?" Sally asked

"An Alien? Hmmm" Charlie Brown thought hard. He recounted in his head the events of yesterday. Walking to school with Linus, learning about the human heart, Linus having two hearts…

"Ah Ha!" he announced. "Sally, I think I know who your alien is, and where to find him.

"Where is he?" Sally asked

"Follow me, I'll show you." Charlie Brown replied. Sally followed Charlie Brown into Linus' garden, all the way to the yellow toyshed.

"So you're telling me the alien is living in this toyshed?" Sally asked.

"Yes, and I also happen to know he responds negatively to the words "Sweet Babboo"" Charlie Brown answered.

"You mean Linus is an Alien!?" Sally retorted, surprised. The door to the yellow toyshed opened.

"Yes" Linus replied, his head peeking out of the door. "I am a Time Lord. Would you both like to take a look inside?" He asked them.

"Is there much to see?" Charlie Brown asked "It doesn't look that big."

"You'd be surprised." Linus answered, walking further into the toyshed. Charlie Brown and Sally followed him inside.

"Welcome to the TARDIS!" Linus announced.

"It's bigger on the inside!" Both Charlie Brown and Sally remarked.

"How is that possible?" Sally asked.

"The proper explanation would be that it's dimensionally transcendental, which basically means it has more than 3 dimensions." Linus explained. "This is a spaceship, by the way"

"Where can it go?" Sally asked

"Anywhere in the universe, any point in time." Linus replied.

"I want to go to the prettiest planet in the galaxy!" Sally demanded.

"I'll try my best." Linus answered, as he typed in the space-time co-ordinates. "Hold on to the railing" he warned. The TARDIS' ride can be a bit bumpy sometimes."

"Got it." Charlie Brown replied, grabbing the railing. Linus pulled the lever. The TARDIS made its usual VWORP VWORP VWORP sound before dematerialising and hurtling through space.

"Where are we going?" Sally asked.

"I'll tell you when we get there." Linus replied. When the TARDIS stopped, everyone could tell from looking out of the window that they were on a strange planet, filled with futuristic buildings.

"Clearly, the TARDIS' idea of beauty is different to what you had in mind." Linus told Sally.

"Well where are we?" Sally asked.

"The TARDIS says this is the year 8182 on the planet Xenon, home of the Whifferdills."

"Who are the Whifferdills?" Charlie Brown asked.

"The Doctor's book said they are a race of shapeshifting creatures, but other than that, it doesn't say much else." Linus answered. "Shall we go and see?" he asked.

The three of them ventured out onto the planet. The city in front of them was vast, with tall buildings built in shapes that definitely symbolised that they were in the 82nd Century. It concerned Linus that the city seemed quieter than you would expect of a city of this size. Even so, it didn't take long before a Whifferdill showed up in front of them, disguised as a Parrot.

"Hello." The Parrot said to Linus. "And who might you be?" he asked

"I'm Linus, and this is Sally and Charlie Brown, my companions." Linus replied.

"My name is Praline. I am a shapeshifting whifferdill, currently morphed as a parrot." Praline told them, as he perched on Sally's shoulder.

"I see you've chosen to be a Norwegian Blue." Sally remarked.

"I got the idea from a TV show I watched." Praline replied.

"So, Praline, where are we, and why do the streets seem empty?" Sally asked.

"Well, Sally, Linus, Charlie Brown, recently the city was rocked by a most heinous crime." Praline began. "A bank heist."

"A bank heist? Good grief." Charlie Brown remarked.

"Calm down, Charlie Brown." Linus told him. "On a scale of fisticuffs to full scale planetary invasion, a bank robbery is only halfway along the scale." He continued.

"That is of course, until you consider that this planet, and the nature of the inhabitants that live here, require the banks to be some of the most secure places in the galaxy." Praline replied.

"Oh yes, I should have remembered. Your people can shapeshift into pretty much any being they wish, so the bank would have to be safeguarded against every shape of being imaginable." Linus realised. "And if the most secure building in the galaxy has been broken into, that means…"

"That nowhere is safe" Praline said, finishing Linus' sentence.

"So, where first?" Charlie Brown asked.

"Straight to the bank, Charlie Brown. We have an investigation to do!" Sally replied, in a playfully serious manner.

The three of them went further into the city, guided by their new acquaintance Praline, who, having shown them a few sights, such as the Building of Unending Tallness (10km tall, for the record), and the Seruza Café (known for its 20th Century architecture), led them straight to the bank.

The bank was an imposing structure, much as you would expect a high security bank to look like, looking rather square, and its walls had sharp and pointy corners. The bank's name shone across the entrance doors. It read "Xenon Prime Bank". Praline entered the automatic double doors first, followed by Linus, Sally, and Charlie Brown. The bank interior was relatively well organised compared to the outside of the building, with wooden flooring and leather chairs. The group walked up to the reception desk. A Whifferdill with the appearance of a tall, thin woman was sitting at the desk.

"Good morning." Said the receptionist. "How can I help you?"

"We are here to investigate how the 'most secure' bank in the galaxy could be subject to a robbery." Linus told her.

"With the objective of having the culprit apprehended." Sally added.

"I'll see what I can do." The receptionist answered. She went to the back of the reception office, apparently trying to ring someone, as far as the group could see. When the receptionist's call was finished, she went back to her position on the front desk. "The Manager is waiting for you in his office, on the door to your right. Good luck on your case." She said to them.

They knocked on the door. "Come in." came a voice from inside the room. Linus, Sally, and Charlie Brown entered, followed by Praline. When they were inside, the Manager motioned for them to sit down. The manager was well dressed, if rather pudgy, and wore a black suit and tie. The manager began "So who are you people anyway?"

"My name is Linus Van Pelt, and these are my companions Sally and Charlie Brown, and also our Whifferdill friend Praline."

"We heard from him that your bank was robbed recently." Charlie Brown added.

"And he would be right." The Manager responded. "And we're no closer to catching the culprit, either. The Police were here yesterday, and they found no evidence of a break-in at all."

"Strange." Said Linus. "Do you think that your own employees could be behind this?"

"The Police tried to call them in for questioning, but when they rang, none of them were at their homes, apart from the receptionist, who was found not to be a culprit." The Manager replied.

"An odd case indeed" Linus began. "We'll see what we can do." Linus, Sally, Charlie Brown and Praline got up out of their seats and left the Manager's office. Once they were back in the main reception area, Linus and the others sat down on leather chairs, Praline perching on one of the armrests. "Sally," Linus began "I know you like being an Ace Detective and everything, but did you really have to drag us into this mess?"

"I never dragged anything. You were the one to take us here." Sally responded.

"I know it's partially my fault, Sally, but you were the one who got us to investigate. We could have just as easily gone back to the TARDIS and searched for a different planet, but you insisted on solving this case.

"Do you have a problem with me wanting to do investigations?" Sally asked.

"It's not that." Linus replied. "It's just, my father only let me bring you guys along on the condition that none of you would get hurt and…"

"Are you saying this is dangerous?" Sally interrupted.

"We're trying to solve a bank robbery on a planet inhabited by shapeshifting aliens. I wouldn't call it the safest thing in the world, no." Linus replied.

"Speaking of which, how are we going to solve this?" Charlie Brown asked.

"I don't know yet. We should go back to the TARDIS to think it over." Linus replied. They got up, and left the bank out of the front entrance. Praline flew on ahead, leading Linus, Sally, and Charlie Brown back to the TARDIS, before perching on the roof to keep watch for any intruders. The three adventurers entered the TARDIS, heading off into the kitchen for a quick break, and to discuss their plan.

"Any ideas?" Charlie Brown asked.

"I want to know why the employees were not at their homes when the police came to call." Sally demanded.

"Good point. It would seem odd that no one would be home, until you realise that the inhabitants of this planet are shapeshifters, so…"

"The robbers stole the identities and appearance of the people working at the bank!" Sally concluded.

"And the security wouldn't have suspected a thing!" Charlie Brown added.

"Most likely the security guards were replaced as well" Linus added. "They wouldn't want to risk getting caught."

"So how do we catch them?" Charlie Brown asked.

"The plan is" Linus began, "firstly, we go back to the bank, asking to interview the workforce. Then, we ask them some basic questions, such as what they know about the bank, and who their friends are. When they begin to contradict each other, we'll ask them to reveal themselves, and where they're hiding the real employees. Then we arrest the criminals and set about freeing the captive employees. Understood?"

"What if the criminals are hostile?" Charlie Brown asked.

"If it gets too dangerous, we'll run, and try to get the police to help." Linus replied, somewhat disappointed in himself that he glossed over a crucial part of his plan. "You guys ready?" Linus asked them.

"Yep. Ready!" Sally said.

"I'm also ready!" Charlie Brown said. The three of them began to make their way towards the console room. On the way to the TARDIS control room, Sally heard a 'ding!' noise emanating from one of the many cupboards. She opened the cupboard where she thought the dinging noise was coming from. Inside the cupboard was a small machine. Sally looked at the small machine with an expression of puzzlement, since she had never seen the machine before, and did not understand its purpose. Despite that, she thought it would be worth bringing it along with them, so she picked it up, and put it into the front right pocket of her longcoat, before running off to catch up with the others. When she got to the control room, Linus and Charlie Brown were already waiting.

"How long have you been waiting for me?" Sally asked.

"About a minute." Linus replied.

"I'm sorry I kept you waiting." Sally said. Are we going then?" she asked.

"Yes. Let's go." Linus said, as they walked their way through the TARDIS door. Praline flew off of the roof of the TARDIS, leading ahead of them as they went back to the bank.
