“Upon my word, when you come to think of it,” he said, “it is a coincidence, sure!  Two men murdered within twenty-four hours, and I seem to have been the last person who knew them, to speak to either.  Tell you what, Mr. Jacks, if this goes on I shall get a bit scared.  I think I shall let the London business alone and go on over to Paris.”

The Inspector smiled.

“I fancy your nerves,” he remarked, “are quite strong enough to bear the strain.  However, I am sure you will not mind telling me exactly why Mr. Richard Vanderpole, Secretary to the American Embassy here, should have come to see you on Thursday night.”

“Why, that’s easy,” Mr. Coulson replied.  “You may have heard of my firm, The Coulson & Bruce Company of Jersey City.  I’m at the head of a syndicate that’s controlling some very valuable patents which we want to exploit on this side and in Paris.  Now my people don’t exactly know how we stand under this new patent bill of Mr. Lloyd George’s.  Accordingly they wrote across to Mr. Blaine-Harvey, putting the matter to him, and asking him to give me his opinion the moment I arrived on this side.  You see, it was no use our entering into contracts if we had to build the plant and make the stuff over here.  We didn’t stand any earthly show of making it pay that way.  Well, Mr. Harvey cabled out that I was just to let him know the moment I landed, and before I opened up any business.  Sure enough, I called him up on the telephone, an hour or so after I got here, and this young man came round.  I can tell you he was all right, too,—­a fine, upstanding young fellow, and as bright as they make em.  He brought a written opinion with him as to how the law would affect our proceedings.  I’ve got it in my room if you’d care to see it?”

Mr. Jacks listened to his companion’s words with unchanged face.

“If it isn’t troubling you,” he said, “it would be of some interest to me.”

Mr. Coulson rose to his feet.

“You sit right here,” he declared.  “I’ll be back in less than five minutes.”

Mr. Coulson was as good as his word.  In less than the time mentioned he was seated again by his companion’s side with a square sheet of foolscap spread out upon the round table.  The Inspector ran it through hurriedly.  The paper was stamped American Embassy,’ and it was the digest of several opinions as to the effect of the new patent law upon the import of articles manufactured under processes controlled by the Coulson & Bruce syndicate.  At the end there were a few lines in the Ambassador’s own handwriting, summing up the situation.  Mr. Coulson produced another packet of letters and documents.

“If you’ve an hour or so to spare, Mr. Jacks,” he said, “I’d like to go right into this with you, if it would interest you any.  It’s my business over here, so naturally I am glad enough of an opportunity to talk it over.”

Mr. Jacks passed back the paper promptly.
