Thus a second time my plans were interrupted, for my expedition that
night ultimately led me to Bow Street, whence, after certain formalities
had been observed, I departed for my chambers, the mysterious pigtail
in my pocket. Failing the presence of Durham, the pigtail must have been
retained as evidence, but:
“We shall know where to find it if it's wanted, Mr. Knox,” said the Yard
man, “and I can trust you to look after your own property.”
The clock of St. Paul's was chiming the hour of two when I locked the
door of my chambers and prepared to turn in. The clangour of the final
strokes yet vibrated through the night's silence when someone set my own
door bell loudly ringing.
With an exclamation of annoyance I shot back the bolts and threw open
the door.
A Chinaman stood outside upon the mat!
