It was no very unusual thing for Mr. Lestrade, of Scotland
Yard, to look in upon us of an evening, and his visits were wel-
come to Sherlock Holmes, for they enabled him to keep in touch
with all that was going on at the police headquarters. In return
for the news which Lestrde would bring, Holmes was always
ready to listen with attention to the details of any case upon
which the detective was engaged, and was able occasionally
without any active interference, to give some hint or suggestion
drawn from his own vast knowledge and experience.
On this particular evening, Lestrade had spoken of the weather
and the newspapers. Then he had fallen silent, puffing thoughtfully
at his cigar. Holmes looked keenly at him.
"Anything remarkable on hand?" he asked.
"Oh, no, Mr. Holmes -- nothing very particular."
"Then tell me about it."
