"The truth is that the gentleman told me that he was a detective and that I was to say nothing about him to anyone." "My good fellow, this is a very serious business, and you may find yourself in a pretty bad position if you try to hide anything from me.

You say that your fare told you that he was a detective ?" "Yes, he did." "When did he say this ?" "When he left me." "Did he say anything more ?" "He mentioned his name." Holmes cast a swift glance of triumph at me.

"Oh, he mentioned his name, did he?
That was imprudent.

What was the name that he mentioned ?" "His name," said the cabman, "was Mr.Sherlock Holmes." Never have I seen my friend more completely taken aback than by the cabman's reply.

For an instant he sat in silent amazement.
Then he burst into a hearty laugh.
"A touch, Watson--an undeniable touch!" said he.
