"Have you mixed the cocktails? You'd better do that. Serve them in about twenty minutes. And you'd better go up and warn Mr. Varcek not to become involved in anything messy before dinner."

Walters yes-ma'am'd her and started toward the attic stairway. Rand and Gladys went into the gunroom; Rand turned to the left, picked a pistol from the wall, and carried it with him as he guided Gladys toward the desk in the corner.

"You think Walters stole them?" she asked.

"So far, I'm inclined to. Have you told any of the others, yet?"

"Oh, Lord, no! They'd all be sure that I stole them myself. I'm counting on you to get them back with as little fuss as possible. Do you think that was why Rivers was killed? After all, when a lot of valuable pistols disappear, and a crooked dealer is murdered, I'd expect there to be a connection."

"There could be. Did you ever hear any stories about Mrs. Rivers and this young fellow Gillis who works in Rivers's shop?"

Gladys laughed. "Is that rearing its ugly head in public, now?" she asked. "Well, there's nothing like a good murder to shake the skeletons out of the closets. Not that this particular skeleton was ever exactly hidden. The stories are numerous, and somewhat repetitious; Cecil and Mrs. Rivers would be seen together, at roadhouses and so on, at what they imagined was a safe distance from Rosemont, and it was said that when Rivers was away over night, Cecil was never seen to leave the Rivers place in the evenings. Might this be relevant to Rivers's sudden demise?"

"It could be." Rand was keeping one eye on the hall door and the other on the head of the spiral stairway. "Don't mention outside what I told you about Farnsworth having this brainstorm about Stephen Gresham. If it got out, it might hurt Gresham professionally. The fact is, Gresham has just retained me to investigate the Rivers murder for him. That won't interfere to any great extent with the work I'm doing here; if necessary, I'll bring a couple of my men in from New Belfast to help me on the Rivers operation." He broke off abruptly, catching a movement at the head of the spiral, and lifted the pistol in his hand, as though showing it to Gladys. "See," he went on, "it has two hammers and two nipples, but only one barrel. It was loaded with two charges, one on top of the other; the bullet of the rear charge acted as the breech-plug for the front charge.... Oh, Walters!" He affected to catch sight of the butler for the first time. "Bring me that .36 Walch revolver, will you?"

"Yes, sir." Walters, crossing the room, veered to the right and went to the middle wall, bringing a revolver over to the desk. It was a percussion weapon with an abnormally long cylinder. "The cocktails are served," he announced.

"We'll be down in a moment; you can put these back where they belong when you find time," Rand told him. "Now, here," he said to Gladys. "This is the same idea, in a revolver. Six chambers, two charges in each. In theory, it was a good idea, but in actual practice ..."
