The Window at the White Cat — Mary Roberts Rinehart

Politics and Poker... that was the occupation and the preoccupation of the members of the White Cat Club. Once on the inside, a man's business was his own and nobody gave a damn if he was the mayor of the town or the champion poolplayer of the first ward. It was a noisy, crowded, masculine kind of retreat, which explained the sign that hung proudly over the door: "The White Cat Never Sleeps." But murder entered the wakeful chambers of the White Cat and its victims slept the deep, long sleep of the dead.
