I happened to know an Englishman employed as clerk to a firm of Dutch forwarding agents whose offices were in the Dam, and this man, whose name was Graham, I at once sought.

We went out to a café together, and I explained the object of my visit, namely, the investigation of the death of Baron van Veltrup. Graham at once regarded me with considerable astonishment, for very naturally he could not make out why I should take such a keen interest in the death of one of the richest men in Holland.

“The Baron died of heart failure,” my friend said. “The doctors are agreed upon that. His valet told some extraordinary story, but no credence has been placed in it. There has been a good deal in the papers concerning the unfortunate affair, but the excitement has now all died down. The Baron was, I believe, buried yesterday.”

“I know that there is no suspicion that death was due to foul play, Graham,” I said. “But I confess that in face of certain knowledge I possess I am not altogether satisfied with the doctor’s conclusion.”

My friend smiled incredulously.

“At first, the police were, I heard, inclined to suspect foul play. But after full investigation they are now quite satisfied as to the cause of death.”

“Be that as it may, I intend to make a few discreet inquiries,” I replied resolutely. “I want you, if you will, to assist me.”

He smiled again in undisguised disbelief.

“Of course you are at liberty to express your own opinion,” he said with some reluctance. “And if you wish, I will assist you. But I really think, Garfield, that you will be only wasting your time—and mine.”
