but stupidity, luck, and a yellow
wig is required of him who pursues it."

"This man is an impostor," whispered Le Coq to Hawkshaw.

"I've known that all along by the mole on his left wrist," returned
Hawkshaw, contemptuously.

"I suspected it the minute I saw he was not disguised," returned Le Coq,
knowingly. "I have observed that the greatest villains latterly have
discarded disguises, as being too easily penetrated, and therefore of no

"Silence!" cried Confucius, impatiently. "How can the gentleman proceed,
with all this conversation going on in the rear?"

"It was in this way that I treated the strange case of the lost tiara,"
resumed the stranger. "Mental concentration upon seemingly insignificant
details alone enabled me to bring about the desired results in that

servants, hastily entering, informed me of the robbery. I changed my mind
in respect to my midnight walk immediately upon receipt of the news, for I
knew that before one o'clock some one would call upon me at my lodgings
with reference to this robbery. It could not be otherwise. Any mystery of
such magnitude could no more be taken to another bureau than elephants
could fly--"

"They used to," said Adam. "I once had a whole aviary full of winged
elephants. They flew from flower to flower, and thrusting their
