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, the body was again interred. But I was not satisfied; and confident that this death had not been a natural one, I entered upon one of those secret and prolonged investigations which for so many years have constituted the pleasure of my life. 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 contrary, requested to know if in her visit to Philadelphia she had noted among her husband's effects anything that was new or unfamiliar to her. "For he received a package while there," I explained, "and though 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 said whether or not you found anything among your husband's effects that can explain this mystery," I suggested.
She at once became attentive.
