The priest glanced at his watch. "Four o'clock?"
"I should think that would do it," said Lord Darcy.
Father Bright nodded wordlessly and left the room.
Dr. Pateley took off his pince-nez and polished the lenses carefully with a silk handkerchief. "How long will your spell keep the body incorrupt, Master Sean?" he asked.
"As long as it's relevant. As soon as the case is solved, or we have enough data to solve the case—as the case may be, heh heh—he'll start to go. I'm not a saint, you know; it takes powerful motivation to keep a body incorrupt for years and years."
Sir Pierre was eying the gown that Pateley had put on the table. The button was still in place, as if held there by magnetism. He didn't touch it. "Master Sean, I don't know much about magic," he said, "but can't you find out who was wearing this robe just as easily as you found out that the button matched?"
Master Sean wagged his head in a firm negative. "No, sir. 'Tisn't relevant sir. The relevancy of the integrated dress-as-a-whole is quite strong. So is that of the seamstress or tailor who made the garment, and that of the weaver who made the cloth. But, except in certain circumstances, the person who wears or wore the garment has little actual relevancy to the garment itself."
"I'm afraid I don't understand," said Sir Pierre, looking puzzled.
"Look at it like this, sir: That gown wouldn't be what it is if the weaver hadn't made the cloth in that particular way. It wouldn't be what it is if the seamstress hadn't cut it in a particular way and sewed it in a specific manner. You follow, sir? Yes. Well, then, the connections between garment-and-weaver and garment-and-seamstress are strongly relevant. But this dress would still be pretty much what it is if it had stayed in the closet instead of being worn. No relevance—or very little. Now, if it were a well-worn garment, that would be different—that is, if it had always been worn by the same person. Then, you see, sir, the garment-as-a-whole is what it is because of the wearing, and the wearer becomes relevant."
