shortly after breakfast time my 'phone bell rang. It was the editor of
the _Planet_, to whom I had been indebted for a number of special
commissions--including my fascinating quest of the Giant Gnu, which,
generally supposed to be extinct, was reported by certain natives and
others to survive in a remote corner of the Dark Continent.

Readers of the _Planet_ will remember that although I failed to
discover the Gnu I came upon a number of notable things on my journey
through the almost unexplored country about the head-waters of the
Niger.

"A most extraordinary case has cropped up," he said, "quite in your
line, I think, Addison. Evidently a murder, and the circumstances seem
to be most dramatic and unusual. I should be glad if you would take it
up."

I inquired without much enthusiasm for details. Criminology was one of
my hobbies, and in several instances I had traced cases of alleged
haunting and other supposedly supernatural happenings to a criminal
source; but the ordinary sordid murder did not interest me.

"The body of Sir Marcus Coverly has been found in a crate!" explained
my friend. "The crate was being lowered into the hold of the S.S.
_Oritoga_ at the West India Docks. It had been delivered by a
conveyance specially hired for the purpose apparently, as the
_Oritoga_ is due to sail in an hour. There are all sorts of curious
details but these you can learn for yourself. Don't trouble to call at
the office; proceed straight to the dock."

"Right!" I said shortly. "I'll start immediately."
