rucible there, the password is of my own choosing
and is written only in a book that no one but the manager ever sees,
and my key is the sole one in existence."

"No duplicate or master-key?"

"Neither. If a key is lost it takes a skilful mechanic half-a-day to
cut his way in. Then you must remember that clients of a safe-deposit
are not multitudinous. All are known more or less by sight to the
officials there, and a stranger would receive close attention. Now,
Max, by what combination of circumstances is a rogue to know my
password, to be able to forge my signature, to possess himself of my
key, and to resemble me personally? And, finally, how is he possibly
to determine beforehand whether there is anything in my safe to repay
so elaborate a plant?" Mr. Carlyle concluded in triumph and was so
carried away by the strength of his position that he drank off the
contents of his second cup before he realized what he was doing.

"At the hotel I just spoke of," replied Carrados, "there was an
attendant whose one duty in case of alarm was to secure three iron
doors. On the night of the fire he had a bad attack of toothache and

all the engines were down at the other end of the city."

Mr. Carlyle committed himself to a dubious monosyllable. Carrados
leaned forward a little.

"All these circumstances formed a coincidence of pure chance.
Is it not conceivable, Louis, that an even more remarkable series
might be brought about by design?"

"Our tawny friend?"

"Possibly. Only he was not really tawny." Mr. Carlyle's easy attitude
suddenly stiffened into rigid attention. "He wore a false moustache."

"He wore a false moustache!" repeated the amazed gentleman. "And you
cannot see! No, really, Max, this is beyond the limit!"

"If only you would not trust your dear, blundering old eyes so
implicitly you would get nearer that limit yourself," retorted
Carrados. "The man carried a five-y
