ou see what I mean. As a result, the image in the mind of
the dying person is returned to the retina. By using the proper
sorcery, this image can be developed and the last thing the dead man
saw can be brought out.

"But it's a difficult process even under the best of circumstances,
and usually the conditions aren't right. In the first place, it
doesn't always occur. It never occurs, for instance, when the person
is expecting the attack. A man who is killed in a duel, or who is shot
after facing the gun for several seconds, has time to adjust to the
situation. Also, death must occur almost instantly. If he lingers,
even for a few minutes, the effect is lost. And, naturally if the
person's eyes are closed at the instant of death, nothing shows up."

"Count D'Evreux's eyes were open," Dr. Pateley said. "They were still
open when we found him. How long after death does the image remain?"

"Until the cells of the retina die and lose their identity. Rarely
more than twenty-four hours, usually much less."

"It hasn't been twenty-four hours yet," said Lord Darcy, "and there is
a chance that the Count was taken completely by surprise."

"I must admit, my lord," Master Sean said thoughtfully, "that the
conditions seem favorable. I shall attempt it. But don't put any hopes

"I shan't. Just do your best, Master Sean. If there is a sorcerer in
practice who can do the job, it is you."

"Thank you, my lord. I'll get busy on it right away," said the
sorcerer with a subdued glow of pride.

Two hours later, Lord Darcy was striding down the corridor of the
Great Hall, Master Sean following up as best he could, his
_caorthainn_-wood staff in one hand and his big carpet bag in the
other. He had asked Father Bright and the Countess D'Evreux to meet
him in one of the smaller guest rooms. But the Countess came to meet
him.

"My Lord Darcy," she said, her plain face looking worried and unhappy,
"is it true that you suspect Laird and Lady Duncan of this murder?
Because, if so, I must--"

"No longer, my lady," Lord Darcy cut her off quickly. "I think we can
show that neither is guilty of murder--although, of course, the black
magic charge must still be held against Laird Duncan."

"I understand," she said, "but--"

"Please, my lady," Lord Darcy interrupted again, "let me explain
everything. Come."

Without another word, she turned and led the way to the room where
