Sherlock watched as the taxi drove off, turned the corner and disapppeared, leaving them stood alone in this slightly eerie place. He gazed towards the Thames as John spoke, visualising the young woman running for her life with someone in pursuit. "It's possible," he nodded. "Although I'd need to see her clothes before I could say for certain whether she was alive or dead when she got to the river. She could have been taken there after she was killed."
Then he turned his attention back towards the power station, and an old rickety looking door half falling off its hinges. The detective approached it and ran his fingers along the top of the frame. "Someone's been in here recently, last 24 hours, although I do know a couple of homeless guys sleep here occasionally. Could be them."
He dug his hand in his left hand pocket and brought out the torch, flicking it on before he pushed open the door and stepped into the dark vast space. Inside there was a large hall with all kinds of old machines and devices, gathering rust and dust and cobwebs, empty cardboard boxes and stacks of crates, a couple of rotting sleeping bags in one corner from previous homeless inhabitants.
Sherlock swept the torch around the room, getting a first impression before he began to look for smaller details, noticing the echo of their footsteps on the stone floor and purposely starting to take smaller, lighter steps, although, if anyone was in here, they most probably would have heard them come in.
