Holmes warns Watson of Moriarty

1 Watson's ground-floor window glows amber in a soot-dark London terrace at dusk

2 Pale, gaunt Holmes stands in the doorway as Watson looks up from his book with concern

3 Holmes bolts the closed shutters in the lamp-lit room while Watson watches from his desk

4 Under the green-shaded lamp, Holmes shows Watson two torn, bleeding knuckles

5 Holmes leans forward in his armchair, tracing an unseen web, a cigarette in his hand

6 Tall, stooped Moriarty fills the doorway, swaying his head and peering at the detective

7 Moriarty sorrowfully shakes his head, telling Holmes he will never stand in the dock
