Aching and groggy, The Doctor came to his senses. For a moment he hesitated to open his eyes, for fear of what he may see. His memory of the previous events hit him quickly, and he felt sick that he had done that, that he had nearly done that, regardless of whether or not he had been under control of some mysterious force. He tried to push aside his shame and decided that whatever faced him out there would be better faced with his eyes open.

His eyes felt sticky, but he could see clearly when he opened them. He was not, as he had feared, still in the bar. Rather he was in what appeared to be a church of sorts, and over him stood a cat nun, smiling down at him.

"You had a close call there," she said soothingly. "Luckily we keep some of our sisters on patrol. Sister Purvience found you before it was too late..." she trailed off for a moment, and The Doctor looked quizzically at her.

"What do you mean... too late?"

"Ahh, you don't know..." she paused momentarily, but quickly continued. "I'm sure you noticed how you lost control of yourself back there. Well, those women, those things, they're not from this planet, this New Earth. They began showing up a few months ago, and since then they have been using their mysterious powers to harvest the people of this planet."

Upon hearing this, The Doctor was back to his take-charge self. "What do you mean, harvest? That's a rather interesting word to use, isn't it?" He sprang up from the bed the nuns had put him in, ignoring the ache in his head.

The cat nun paced toward the small window, looking meloncholy. "They are literally eating their victims, sir," she sighed, "They draw people to them using some mysterious power, then... Well, we sisters don't typically speak of such thing, but... when they draw their victims into the throws of passion, they... they... use their teeth." She sighed and turned away, embarrassed.

The Doctor spent only a moment working that one out, then he immideately began searching the halls of his mind for clues about what these creatures could be.

"Don't worry, Sister," The Doctor said confidently, "I'll find a way to save your planet!"

The cat nun smiled at him. "I hope you can. And may the Cat God watch over you and save your soul!"

The Doctor sat in a pew, thinking. After a moment he said "What is your name, sister?"

"I am Sister Meowline. I will do all I can to help you rid our world of those Sireens!"

"Sireens?"

"Yes...that much I can say. They are from a place called Sireen. I don't know where it is but that is what they call themselves, 'Sireens.' There are so many of them plaguing the city now!"

"Sireens..." The Doctor was turning the it over in his mind. He couldn't think of where he might have heard of such creatures before. He couldn't seem to think of a way to defeat them. He looked at Meowline "Can you tell me anything more about them? No matter how basic the information, it might be helpful!"

The nun thought a moment and then sat next to him. "Ok, well...they all seem to be female and their effects only work on males, it seems. The other sisters and I don't like being around them but we don't come under their spell. I mean, we have had them lash out at us but they don't have the same powers on us. Maybe it is because we are protected by a higher power."

"I'll bet it's some kind of pheromone." The Doctor wondered allowed. "If I could get a sample of it..."

"Well, we have been trying to study them ourselves. Sister Meowlotta has a small laboratory here and she has tried to study it." She lowered her voice a little "some of us have talked about trying to catch one of them...maybe even dissect it!" The glee in her voice at the description of violence was disarming coming from a nun!

"Sister Meowline, who is this visitor?" A second cat nun was quickly walking towards them. The Doctor quickly recognized that she must be in a higher position in the convent. Her robes were slightly different. She was shorter and a bit plumper than Meowline.

"This is The Doctor!" Sister Meowline said, rising to her feet and bowing slightly to her superior.

"How did you know my name?" The Doctor asked.

"Oh, I heard that Sireen in the bar say it. I was following you two for a little while. I wanted to wait until you were alone to act. The place was packed with Sireens, you know! That is a common hangout for them. Very dangerous! But when I saw you walking down the street with her..." Meowline blushed a little. The doctor could tell even though the evidence was hidden beneath fur "well, I knew you were someone who wasn't from around here and someone who might be...interesting." She smiled.

The other nun cleared her throat.

"Oh dear!" Meowline snapped out of whatever thought had been consuming her "I'm so sorry! This is Sister Meowrita." She nodded to the other nun "I'm sorry, sister!"

"Yes." Meowrita said. "You should be. You seem to be baring your soul to this stranger. Are you quite sure that is a good idea? Perhaps he is not someone we can trust."

"Oh, you can trust me! I'm the Doctor!"

"Really, that's just what I would expect someone I couldn't trust to say!" Meowrita scowled.

"So if I said you couldn't trust me would that make you trust me?"

"Certainly not!"

"I see. There is nothing I can say to make you trust me. But perhaps there is something I can do to win you over, Sister!" The doctor nodded to something behind her. "You see there? It's a very advanced technology but I noticed it quickly!" He walked to the altar where a large cross was hanging.

The nuns followed him, both looking quite confused. Meowrita seemed very angry as he moved his arm up the side of the large cross. "Don't touch that!" she yelled "It is the sacred cross of the Cat God!"

The doctor drew his hand away from it quickly "Yes, yes. But I thought you might want to know that someone has been spying on you!" He held out his hand to the nuns to show them a small piece of metal.

"What is it?" Meowline asked.

"He defaced our sacred cross!" Meowrita spat.

"It's a listening device. A very nice one indeed! To the untrained eye it is nearly invisible!" He had taken out his sonic screwdriver and was moving it across the metal object. "It's transmitting to a place nearby. I can probably locate it. But they probably heard us and know we are coming already. We'll have to hurry!" He had already begun running in the direction of the transmission location and the nuns were following.

"It must be the Sireens! They must have been listening to us!" Meowline gasped as they went.

Meowrita still looked angry and untrusting of The Doctor but she ran along with him.

"I suppose I should have disabled it before saying anything" The Doctor noted. "But I did recently fall under the influence of some strange pheromones. I guess I wasn't thinking quite right yet." They had left the church and quickly made their way down a beat up street, into an alley a few blocks away, and soon enough the doctor halted and put a finger to his lips. Though they probably didn't have the element of surprise there was still no sense in just barging in. Anything could be waiting for them. The doctor motioned to the nuns and whisper "the trail ends here. it should be just through this door. Stay behind me." He moved the sonic screwdriver over the lock and in a quick movement threw the door open.

As he had expected there was no one on the other side. The occupants had fled in a hurry. But he was certain that in their haste they had surely left many clues behind.
