“Well, first of all, the blow on the head had, of course, nothing whatever to do with the death. You saw yourself that there had been next to no bleeding. The wound was inflicted some time after death—no doubt to create the impression of an attack by a gang. Similarly with the cuts and scratches on the arms. They are the merest camouflage.”

“Exactly. Your colleague—”

“My colleague, as you call him, is a fool,” snorted the doctor. “If that’s a specimen of his diagnosis, I should think there would be a high death-rate in Crow’s Beach. That’s by the way. You want the cause of death?”

“Chloroform?”

“Possibly. I opened the body but found no special symptoms suggestive of poisoning or anything. I have removed the necessary organs and sent them to Sir James Lubbock for analysis at your suggestion, but candidly I expect nothing from that. There was no odour of chloroform on opening the thorax. Either the time elapsed since the death was too long, as is very possible, seeing how volatile the stuff is, or the dose was too small. I found no indications of any heart weakness, so that, to produce death in a healthy young girl, chloroform would have had to be administered over a considerable time.”

“Do you think it was administered at all?”

“Yes, I think it was. The burns on the face certainly suggest it.”

“That would also account for the handkerchief found in the car,” said Wimsey.

“I suppose,” pursued Parker, “that it would require considerable strength and determination to administer chloroform to a strong young woman. She would probably resist strenuously.”

“She would,” said the doctor, grimly, “But the odd thing is, she didn’t. As I said before, all the marks of violence were inflicted post-mortem.”
