Calleigh open the bathroom door and switched on the light. The room was a typical bathroom with nothing seeming out of place. Calleigh checked the medicine cabinet which just contained the standard aspirin and a bottle of antacid. She closed the door and began processing the room.

Half way through the room, Calleigh spot a small button hidden behind a towel on the towel rail. She pressed it. She looked around to see what it controlled. She looked around all the walls and the ceiling she took a step back to get a better look and let out a blood curdling scream before blackness engulfed her.

Horatio was signing off on the paperwork for the transport of the freezer in the garage with Adelle.

When they heard scream they glanced at each other, before drawing their guns and running into the house.

Speed dropped the item he was examining and ran to the ladder and quickly climbed and drew his gun ran to the bathroom.

The officer that had been guarding the front door met them by the bathroom door. The bathroom was perfectly normal except Calleigh's kit sat open on the floor with an evidence envelope next to it. But Calleigh was no where to be see.

"Calleigh?" Horatio yelled. There was no response.

"Okay where is she?" Adelle asked.

"No one has entered or left the house other than you sir." The officer told him.

"Search the rest of the house." Horatio instructed. "Speed, look the bathroom over."

"You've got it H."

"The rest of the house is clear, no sign of struggle." Horatio said as he re-entered the bathroom.

"I can't see where she's gone." Speed said.

"Let's think this through logically. A person can't just disappear, especially from a house filled with police officers." Horatio said calmly. "Let's trying calling her cell phone."

Horatio took out his phone and dialled Calleigh's number.

"Horatio she's not outside either." Adelle said coming to the doorway.

"Be quiet for a moment." Horatio instructed.

"Do you hear that?" Speed asked.

"It signs like it's coming from down low maybe under the floor." Horatio said.

"The floor is solid." Speed replied.

"But maybe not as solid as it appears." Horatio ended the call before it could switch to voice mail and redialled.

Speed got down on the ground and pressed his ear to the floor and crawled around to find where the sound was loudest.

"What have you got Speed?" Horatio asked.

"There isn't any grout around these nine tiles" He replied. "Maybe a trap door." He looked up.

"You weight more than Calleigh, so if the floor gave way under her weight it would have under yours or mine. So she had to have touched something." Horatio said.

"But what? Can you see any buttons or switches?" Speed asked.

"We're going to have to find one." Horatio said. "Adelle call an ambulance, keep everyone out while we search."

"You've got it."

"Let's find her."
