respectable, and that seen from behind I looked like the British
Constitution. They said I looked too healthy and too optimistic, and too
reliable and benevolent; they called me all sorts of names at Scotland
Yard. They said that if I had been a criminal, I might have made my
fortune by looking so like an honest man; but as I had the misfortune to
be an honest man, there was not even the remotest chance of my assisting
them by ever looking like a criminal. But at last I was brought before
some old josser who was high up in the force, and who seemed to have

"So I did," said Bull brightly; "but we talked in a pitch-dark room like
a coalcellar. There, you would never have guessed that."

"I could not have conceived it," said Syme gravely.

"It is indeed a new idea," said the Professor.

Their new ally was in practical matters a whirlwind. At the inquiry
office he asked with businesslike brevity about the trains for Dover.
Having got his information, he bundled the company into a cab, and put
them and himself inside a railway carriage before they had properly
