"Doctor, a hypothetical question: if a person were stunned, I mean knocked entirely unconscious, before falling or being thrown into the water, and then perished by drowning, would you expect to find the body, after twelve to thirteen hours of submersion, more or less in the condition of Mrs. Doherty's at the time you made that first examination?"

Edith saw Callista start as if struck in the face. Her dark brows gathered in that quick frown of hers, and she was leaning to Cecil Warner, whispering. She looked, Edith thought, more disgusted than angry. Cecil's poker face remained in control. He only listened, shook his head, patted her hand.

"Oh, hypothetical—well.... I dare say the findings wouldn't be inconsistent. Of course, Mr. Hunter, I looked for any sign of head injury, a matter of routine, and found nothing of the kind."

"Isn't it possible, Doctor, to receive a head injury, perhaps from a padded thing like a sandbag, that won't leave any marks?"

"No superficial marks, maybe. I think you'd find post-mortem evidence, likely subdural hemorrhage."

"Even from a blow that merely stunned?"

With some acid and faraway amusement Dr. Devens remarked: "Even as Coroner's physician, I'm not too versed in the lore of sandbags. But I think that a blow heavy enough to stun, followed very soon by death from another cause, would leave some internal evidence."

"Did you look for such evidence?"

"I did."
