there to be seen on the body any mark of violence,
with the exception of a minute prick upon one of his thumbs.

This speck was so small that it escaped every eye but my own.

The authorities assuring the widow that the doctor's certificate given
her in Philadelphia was correct, he was again interred. But I was not
satisfied; neither do I think she was. I was confident that his
death was not a natural one, and entered upon one of those secret and
prolonged investigations which have constituted the pleasure of my life
for so many years. First, I visited the Colonnade in Philadelphia, and
being allowed to see the room in which Mr. Holmes died, went through it
carefully. As it had not been used since that time I had some hopes of
coming upon a clue.

But it was a vain hope and the only result of my journey to this place
was the assurance I received that the gentleman had spent the entire
evening preceding his death, in his own room, where he had been brought
several letters and one small package, the latter coming by mail. With
this one point gained--if it was a point--I went back to New York.

Calling on Mrs. Holmes, I asked her if, while her husband was away she
had sent him anything besides letters, and upon her replying to the

its contents may have been perfectly harmless, it is just as well for us
to be assured of this, before going any further."

"Oh, you think, then, he was really the victim of some secret violence."

"We have no proof of it," I said. "On the contrary, we are assured that
he died from natural causes. But the incident of the newspaper slip
outweighs, in my mind, the doctor's conclusions, and until the mystery
surrounding that obituary notice has been satisfactorily explained by
its author, I shall hold to the theory that your husband has been made
away with in some strange and seemingly unaccountable manner, which it
is our duty to bring to light."

"You are right! You are right! Oh, John Graham!"

She was so carried away by this plain expression of my belief that she
forgot the question I had put to her.

"You have not told whether or not you found anything among your
husband's effects that can explain this mystery," I suggested.

She at once became attentive.

"Nothing," said s
