"Came by his death," echoed Garth in astonishment. "What do you mean?"

"Why," answered Fanks, seriously, "I mean that the needle used for the tattooing was poisoned; and so--," he shrugged his shoulders, "--the man died."

[CHAPTER IV].

ANOTHER DISCOVERY.

Informed of this astounding fact, Garth stared at his friend in blank astonishment. The detective resumed his cigar, and waited.

"You cannot be in earnest," said the barrister after a pause.

"Why not? The theory is feasible enough. It was proved at the inquest that the man died from blood-poisoning."

"Yes. But it might have been administered in the liquor. The pair had drinks, remember."

"I have not forgotten," said Fanks quietly, "but on your part remember that no trace of poison was found in the stomach; while the blood was so corrupted, as to show that the deceased had been inoculated with some powerful vegetable poison. There was no mark on the body, save the cross on the left arm; and, by your own showing, it was not there when Fellenger went to Tooley's Alley. The assumption is that it was done there; as is more than confirmed by the presence of gunpowder."

"Again, according to Mrs. Boazoph, there was no struggle; therefore the deceased must have passed away quietly. My inference is that this negro desired to kill Sir Gregory--or else he was instructed to do so by some one else who wished for the death of your cousin. What then so easy, as for the negro to have a poisoned needle prepared to execute the tattooing. Quite unaware of the danger, Fellenger--for some unknown reason--would permit the insertion of the fatal needle. As the work went on, he would gradually be inoculated with the poison. When the gunpowder and acids were applied the job would be finished, and he would pull down his sleeve, quite ignorant that to all intents and purposes he was a dead man. Then he sat and chatted with the negro till the end came; when he sank into a state of coma and died. When certain that the death was an assured fact, the negro took his departure. Oh, it is all as plain as day to me;--all excepting one fact."
