It is rather a reflection upon us that we have not as yet even made an arrest, but I think you will also admit that the circumstances of those murders were exceedingly curious." Mr.Coulson knocked the ash from his cigar.
"Well, as to that," he said, "and if we are to judge only by what we read in the papers, they are curious, without a doubt.

But I am not supposing for one moment that you fellows at Scotland Yard don't know more than you've let on to the newspapers.

You keep your discoveries out of the Press over here, and a good job, too, but you wouldn't persuade me that you haven't some very distinct theory as to how that crime was worked, and the sort of person who did it.

Eh, Mr.Jacks ?" "We are perhaps not quite so ignorant as we seem," the Inspector answered, "and of course you are right when you say that we have a few more facts to go by than have appeared in the newspapers.

Still, the affair is an extremely puzzling one,--as puzzling, in its way," Mr.
Jacks continued, "as the murder on the very next evening of this young American gentleman." Mr.Coulson nodded sympathetically.
