Turning away, he tried to get his bearings. There was the distant headland, green now in the sunlight, where Hartle’s body had been found. Using that as his guide, he walked in an easterly direction until he realized that he was coming out of a side street that ended near the water.

The pub was several streets over. Glancing at his watch, he realized that he’d been walking for more than an hour. He swore and was about to turn up toward the pub and his motorcar when another shop window caught his eye.

The display was of all things military. Gold braided tricorns, an assortment of swords, and a polished table where tiny lead soldiers fought pitched battles. There was a rusty halberd, books on military tactics from wars long past, a pistol with a split barrel, and even a well-used Kaiser Wilhelm helmet with its pointed spike, and a long spear that appeared to be East African.

On the spur of the moment, he went inside. The proprietor was an elderly man with streaks of gray in his fair hair, and bright blue eyes. He glanced up from a sock he was mending as the bell over the door jingled, and smiled at Rutledge. “Looking for anything in particular?” he asked in a deep, gruff voice.

“Identity discs from the war. Do you ever see them? Or have them for sale?”

The crinkles around the blue eyes deepened. “There’s no market for that sort of thing. They were rather flimsily made, as a rule. Buttons, now, and uniforms—they turn up. I have a button hook, from the Grenadier Guards. Any number of shell casings, some of them with trench art, others plain. An officer’s whistle, well-polished riding boots with gilt spurs—even several pairs of field glasses.”

Hamish had subsided in his mind, and Rutledge was about to turn away when something caught his eye in the glass display case where he was standing. It contained smaller and more expensive objects kept under lock and key. There were an ivory pipe, a cigarette case made from what appeared to be tortoiseshell, a flint knife, a few American Civil War lead soldiers, and assorted buttons, watches, rings, and other pieces of jewelry inscribed with military insignia.

He pointed to the knife. “What can you tell me about that?”

“It’s said to be quite old. Struck from a single large flint. The gentleman who brought it in told me his grandfather had turned it up while working in his garden. It set him off on a search for an ancient burial site, thinking there might be funeral goods. But to no end.” The proprietor took the object out of the case. “You can see how the blows were struck to shape the blade. Careful,” he added as he passed it to Rutledge. “It’s sharp enough to cut hide.”

Rutledge took the blade. “How was it used?”

“According to a Dr. Butler who comes in from time to time, it would have had a handle, a length of wood with a fork at one end, into which the blade would have been inserted.” He pointed to the blunt end. “See how it’s notched? Rawhide would be wrapped tightly around wood and blade, and perhaps soaked, for a tight fit. If you knew what you were about, you could flense a hide just with the blade, but if you were of a mind to stab a woolly mammoth, you’d need the handle for a sure grip. Short handle for jabbing, longer piece of wood for throwing. Of course, if this is as old as it’s said to be, the wood and the rawhide have long since rotted away. A pity, but there you are.”
