"You seized a spade—"
"It was in my hand," the doctor interrupted, feebly.
"That is right; correct me whenever I am in error. You raised the spade and struck Deever upon the head.
"He fell to the ground, and you, bending over him, were horrified to find that he was dead; or, rather, that he seemed to be.
"Exactly how he came to life I do not know, but it must have been while you were in the midst of your terror, and beginning to wonder what you would do with the body."
"How do you know all this?" asked the doctor, faintly.
"It is simply the only explanation of all the facts. The witness Klein heard the quarrel and the blow. That blow did not fall upon you, and there was nobody else present but Patrick Deever.
"Now, then, he suddenly came to himself. He sprang up. You were amazed. You advanced toward him.
"Believing that you intended to renew the attack, he ran away. He scaled the garden wall, and fled through the little grove toward the river."
"You are reading my mind," exclaimed the doctor, whose amazement acted as a restorative.
