It is clear that this unfortunate man was about to return to New York." "Have you made any inquiries as to this man, Stangerson ?" "I did it at once, sir," said Gregson.

"I have had advertisements sent to all the newspapers, and one of my men has gone to the American Exchange, but he has not returned yet." "Have you sent to Cleveland ?" "We telegraphed this morning." "How did you word your inquiries ?" "We simply detailed the circumstances, and said that we should be glad of any information which could help us." "You did not ask for particulars on any point which appeared to you to be crucial ?" "I asked about Stangerson." "Nothing else?

"Come here," he said, bustling back into the room, the atmosphere of which felt clearer since the removal of its ghastly inmate.

"Now, stand there!" He struck a match on his boot and held it up against the wall.
"Look at that!" he said, triumphantly.

In this particular corner of the room a large piece had peeled off, leaving a yellow square of coarse plastering.

Across this bare space there was scrawled in blood-red letters a single word-- RACHE.
"What do you think of that ?" cried the detective, with the air of a showman exhibiting his show.
