I do not know how far Sherlock Holmes took any sleep that night, but when I came down to breakfast I found him pale and harassed, his bright eyes the brighter for the dark shadows round them. The carpet round his chair was littered with cigarette-ends and with the early editions of the morning papers. An open telegram lay upon the table.

“What do you think of this, Watson?” he asked, tossing it across.

It was from Norwood, and ran as follows:

Important fresh evidence to hand. McFarlane’s guilt definitely established. Advise you to abandon case.

Lestrade.
