“I did, sir, and it was seeing you came from there made me think of them,” replied the landlord. He went back to the bar and got the drinks, which he brought to the fire. It immediately appeared that his interest in crime, as reported in the newspapers, was at least as keen as that of the late Mr. Tovey. But never before had it been his fortune to meet one who had personally known the victims of two unsolved murders.
