"Great Jerusalem! of all the strange, weird and remarkable incidents, this beats them all in its fateful significance. There is the little grave marked Amalie Canfield, died aged four years. Great ginger! here is a nameless Amalie who may have been older than the child Amalie Canfield."

We will here state to those of our readers who have not read Jack's former adventures as related in "Two Wonderful Detectives," that they will understand the detective's excitement as they proceed with the narrative.

Jack did not waste much time in words. He left his rooms, also a note for his brother, his partner as a detective, and started for New Jersey. Fortunately, he caught a train, and an hour later alighted at a station, and rapidly he walked along the road for a couple of miles, when he arrived at a little graveyard. He entered the cemetery and almost ran to a little grave, and dropping down he fixed his eyes on the tombstone, and there he read:

"Amalie Canfield.
"Born, —— ——. Died, December —, 18—."

The detective rose to his feet, his handsome face all aglow, and he again muttered:

"Here is a mystery—a little mystery—but it can be explained. One or the other Amalie died. It's my opinion Amalie Stevens lives, and after all I have at last found the heir to a million. I lose the fortune, but the true heiress will get it. Yes, I'll swear I am on to the final solution, the most successful shadow I shall ever make. It is the greatest catch of my life—yes, although I lose half a million, and I'd rather lose a million than to learn that I have been misled. I must go slow—yes, very slow—but as it stands I believe I've struck it at last."

The detective returned to New York, where he arrived early in the afternoon. He had a close friend, a very wealthy banker, for whom he had done a great service. He proceeded direct to the home of the banker, an old gentleman, but a man of great vigor considering his age, both mentally and physically.

"Hello, Mr. Wonderful," was the banker's salutation as our hero entered his presence. "Where did you come from? I have not seen you for several months."

"No, but I am here now."

"And your presence means that you have made another of your wonderful discoveries."
