They found the knife quite by chance soon after the search was started. The youngest member tripped on the edge of a flat gravestone and fell, facedown in the snow, accompanied by laughter and jeers. As he stumbled he knocked over a vase of dead daffodils that had been standing on the grave and the knife emerged with the rotting stalks of the flowers.

“You lucky bastard,” someone shouted. “I suppose you’ll take the credit for finding it now.”

But they were all pleased that the murder weapon had been found. It encouraged them that they might find something else of significance.

Ramsay was told about the discovery of the knife in Otterbridge. He was at the police station, supervising the setting up of the Incident Room, the arrival of computer terminals, extra phone lines, and piles of paper. Still no-one had found the screens to block off the corner of the Tower garden where the body had been found, and he, too, muttered about inefficiency. His superintendent was giving all his attention to the press and on every news broadcast there was a shot of him pleading earnestly for information about any unfamiliar cars seen in Brinkbonnie on Saturday night.

A group of detectives from Newcastle had been drafted to help and they milled around the Incident Room until Ramsay sent them off to Brinkbonnie to begin the house-to-house enquiry.

Hunter arrived at work elated and energetic after his night in Newcastle, wanting action, immediate results.

“Did you see the Elliots last night?” Ramsay asked.

Hunter nodded.

“Anything?”

“Not much. They weren’t very communicative.” I bet you weren’t either, Ramsay thought. You’d want to get the interview finished as soon as possible so you’d be in Newcastle before your date walked out on you.

“Did Charlie Elliot tell you he’d been to the pub?” Ramsay asked.

“Yes.” If Hunter was impressed by Ramsay’s knowledge, he did not show it.

“What time was he home?”

“About eleven. His father confirmed it.”

“How did he strike you?” Ramsay asked. “Apparently he’s been making a nuisance of himself with Maggie Kerr, the barmaid in the Castle. They were engaged when they were teenagers and he never got over it. Did he seem unbalanced to you?”

“Not unbalanced,” Hunter said. “Moody perhaps.”

“Well,” Ramsay said, “ if he was home by eleven, he can’t have murdered Mrs. Parry. She was still in the Castle then. She definitely left Henshaw’s and went straight to the pub. The barmaid said she was upset, but Henshaw won’t admit that there was any unpleasantness. Perhaps you could make some enquiries in the village. Find out all you can about him. He drives a Rover. See if anyone saw it late Saturday night.”

“Are you coming to Brinkbonnie?”

“Later. I’ve an appointment with the council’s planning officer. I want to find out about these houses.”
