“Was your brother accustomed to report back to Mr. Trevelyan regularly?” Grey asked, glancing over his shoulder. “Whilst watching Sergeant O’Connell, I mean?”

Tom shrugged, looking unhappy.

“Dunno, me lord. Jack didn’t say what it was he was up to; only that it was a special thing Mr. Joseph wanted him to do, and that was why he wouldn’t be in the house for a bit.”

“But you know now? What he was doing, and why?”

An expression of wariness flitted through the boy’s eyes.

“No, me lord. Mr. Trevelyan only said as I should help you. He didn’t say specially what with.”

“I see.” Grey wondered how much of the situation to impart. It was the anxious look on Tom Byrd’s face, as much as anything else, that decided him on full disclosure. Full, that is, bar the precise nature of O’Connell’s suspected peculations and Grey’s private conjectures regarding the role of Jack Byrd in the matter.

“So you don’t think the dead—Sergeant O’Connell, I mean—you don’t think he was just knocked on the head by accident, like, me lord?” Byrd had come out of his mope; the clammy look had left his cheeks, and he was walking briskly now, engrossed in the details of Grey’s account.

“Well, you see, Tom, I still cannot say so with any certainty. I was hoping that perhaps we should discover some particular mark upon the body that would make it clear that someone had deliberately set out to murder Sergeant O’Connell, and I found nothing of that nature. On the other hand . . .”

“On the other hand, whoever stamped on his face didn’t like him much,” Tom completed the thought shrewdly. “That was no accident, me lord.”

“No, it wasn’t,” Grey agreed dryly. “That was done after death, not in the frenzy of the moment.”

Tom’s eyes went quite round.

“However do you know that? Me lord,” he added hastily.

“You looked closely at the heelprint? Several of the nailheads had broken through the skin, and yet there was no blood extravasated.”

Tom gave him a look of mingled bewilderment and suspicion, obviously suspecting that Grey had made up the word upon the moment for the express purpose of tormenting him, but merely said, “Oh?”

“Oh, indeed.” Grey felt some slight chagrin at having inadvertently shown up the deficiencies of Tom’s vocabulary, but didn’t wish to make further issue of the point by apologizing.

“Dead men don’t bleed, you see—save they have suffered some grievous wound, such as the loss of a limb, and are picked up soon after. Then you will see some dripping, of course, but the blood soon thickens as it chills, and—” Seeing the pallid look reappear on Tom’s face, he coughed, and resumed upon another tack.
