"Ha! You detectives have your experiences! I should not have enjoyed spending that especial evening with you. But what an old-world tragedy we are unearthing here! I declare"—and the good lady actually rubbed her eyes—"I feel as if transported back to mediæval days. Who says we are living in New York within sound of the cable car and the singing of the telegraph wire?"
"Some men are perfectly capable of bringing the mediæval into Wall Street. I think Mr. Adams was one of those men. Romanticism tinged all his acts, even the death he died. Nor did it cease with his death. It followed him to the tomb. Witness the cross we found lying on his bosom."
"That was the act of another's hand, the result of another's superstition. That shows the presence of a priest or a woman at the moment he died."
"Yet," proceeded Mr. Gryce, with a somewhat wondering air, "he must have had a grain of hard sense in his make-up. All his contrivances worked. He was a mechanical genius, as well as a lover of mystery."
"An odd combination. Strange that we do not feel his spirit infecting the very air of this study. I could almost wish it did. We might then be led to grasp the key to this mystery."
"That," remarked Mr. Gryce, "can be done in only one way. You have already pointed it out. We must trace the young couple who were present at his death struggle. If they cannot be found the case is hopeless."
"And so," said she, "we come around to the point from which we started—proof positive that we are lost in the woods." And Miss Butterworth rose. She felt that for the time being she, at least, had come to the end of her resources.
Mr. Gryce did not seek to detain her. Indeed, he appeared to be anxious to leave the place himself. They, however, stopped long enough to cast one final look around them. As they did so Miss Butterworth's finger slowly rose.
"See!" said she, "you can hardly perceive from this side of the wall the opening made by the removal of that picture on the stair landing. Wouldn't you say that it was in the midst of those folds of dark-colored tapestry up there?"
"Yes, I had already located that spot as the one. With the picture hung up on the other side, it would be quite invisible."
