Tommy is tall but the window is a good three or four feet above him. Luckily there's a barrel by the drainpipe, and he tips it over to roll it toward the window before setting it upright again. Climbing onto it, he peers in and can clearly see down the corridor, the rows of cells, and the guard sleeping near the fireplace.

Hmm. British police officers are unarmed. Tommy could probably take him if it came to it.
