Murder in the Gunroom by H. Beam Piper

The Lane Fleming collection of early pistols and revolvers was one of the best in the country. When Fleming was found dead on the floor of his locked gunroom, a revolver in his hand, the coroner's verdict was "death by accident." But Gladys Fleming had her doubts. Enough at any rate to engage Colonel Jefferson Davis Rand--better known just as Jeff--private detective and a pistol-collector himself, to catalogue, appraise, and negotiate the sale of her late husband's collection.

There were a number of people who had wanted the collection. The question was: had anyone wanted it badly enough to kill Fleming? And if so, how had he done it? This is a mystery that will keep your nerves on a hair trigger even if you don't know the difference between a cased pair of Paterson .34's and a Texas .40 with a ramming-lever.
