Arrived on the second-floor landing, we were confronted by a solid-looking door on the lintel of which the deceased man’s name was painted in white lettering which still looked new and fresh. Thorndyke knocked at the door, which was at once opened by Stephen Blackmore.

Thorndyke smiled genially, amused, no doubt, by the similarity of Stephen’s remarks to those of mine which he had so recently criticized.
