The Hound of the Baskervilles
or a malevolent agency which is in touch with us, I am conscious always of power and design. When our friends left I at once followed them in the hopes of marking down their invisible attendant. So wily was he that he had not trusted himself upon foot, but he had availed himself of a cab, so that he could loiter behind or dash past them and so escape their notice. His method had the additional advantage that if they were to take a cab he was all ready to follow them. It has, however, one obvious disadvantage.”
“It puts him in the power of the cabman.”
“Exactly.”
“What a pity we did not get the number!”
“My dear Watson, clumsy as I have been, you surely do not seriously imagine that I neglected to get the number? 2704 is our man. But that is no use to us for the moment.”
“I fail to see how you could have done more.”
