Nothing like Sherlock getting back on with a genius episode about Irene Adler to bust your imagination :-).
"Oh, I am interested, Sherlock. It's just that my interest is not on what you're looking for." she said with a seductive smile, concealing all her intentions to him.
"You're not interest in the diamond?" He asked, annoyed by the fact he couldn't read her.
She sighed touching his collar. "The diamond is long gone, Sherlock. You know that." She leaned closer, whispering in his ear. "Accept that you can't win every time, and let me go."
Anger and desire clouded Sherlock's thought for a fraction of a second. The anger of being outwitted by her again made it easier for him to order his body to stop reacting to he proximity and her perfume.
He wouldn't let her foul him again. She would loose this time.
Sherlock stepped back staying at a safe distance from her. "I need to know who was staying in the adjoining room" He said, turning to the baron.
"You think someone in the hotel stole my diamond. How?"
"Through the air vent, obviously. It leads to another room in this hotel and someone passed through it in the night and took your diamond without you or your security seeing it."
"Sherlock, the air vent is too small, only a child could pass through that thing." John said unconvinced. Sherlock just moved his head in his direction. John took some time to understand. "You think a child stole the diamond?" he asked.
Irene smiled amused.
"Or someone the size of a child. You find who was in the room on the other side of the air vent you have your thief, Baron." Sherlock said.
The Baron walked outside the room calling his security and asking them to find out who was in the adjoining the last night.
John walked closer to Sherlock. "So, Irene was telling the truth?" he asked in a whisper.
Shelock didn't answer, just kept staring at Irene, trying to see anything that would betray her. There had to be something he was missing. She was involved in this, he was sure of that. Maybe not in the way he first imagined, but she wasn't innocent.
She stood up and walked to the bar, going through the bottles until she found a white wine that interested her and poured a glass. "So, can I go now?" She asked sipping the wine. "If I run, maybe I can still make the last flight to the States.
After a few moments, the baron returned with three men of his security team. He was pale and a little shaken. "You were right Mr Holmes. The adjoining room was occupied by an American couple with a young boy, they arrived the same day I did and left the hotel in the middle of the night. According to the clerk they ordered a cab to the airport because their flight left at 5 am. They're probably gone, by now."
The Baron went to the bar himself and poured a glass of scotch, taking a big gulp. He looked confused at Irene. "I don't understand what is going on." He said to her, as if pleading for an answer.
She noticed the tension in his brow and neck. Something was worrying him more than just the stolen diamond. Maybe the realization he was totally gone and he was lost. But her senses told her it wasn't just it. She looked back at Sherlock who had shift his gaze from her to the Baron. He was sensing something too.
"Did the clerk give you their names? Anything that could help us find them?" John asked.
The Baron kept looking at Irene and them went to his bed sitting by the side of it.
"Smith, John and Jane. Probably fake names. The security tapes were taken, there's no image of them." The security guard next to Sherlock said.
Sherlock looked at the way the security was positioned and realize something was definitely wrong.
"If you let us take this to the police they can help us track them down." John said.
"That would ruin my reputation." The Baron said beaten. "No, I have to do what they said."
"What who said?" Sherlock asked noticing the small movements of the security men.
The Baron opened the drawer of the bedside table and take a small pistol, pointing it to Irene.
Before anyone can make a movement the two security guards pull their weapons and point them to Sherlock and John, ordering them to don't move.
"I'm sorry, Miss Adler." The Baron said standing up and walking closer to her. "I don't know what is going on, but I need my diamond back."
"I don't have your diamond." Irene said alert, without understanding herself what was going on. "Sherlock just told you who stole it. It wasn't me."
"I need my diamond back." The baron repeated. "And for that to happen, you need to die."
