Zitts looked at the woman with pity in his brown eyes. "Woman, you evidently do not understand the psychology of murder. One always leads to another. It's always been that way. Look at the murder stories of even the blind age of the twentieth century! Thirteen murders, ordinarily, on the first page. Seven on the second, and the balance strung out through the book. It is the aspiration of every collector to find a book with only one murder in it. Personally, for such a work I would offer seventy-five interstellar giant transports each loaded to bursting with ton upon ton of diamonds, emeralds, pearls, sapphires, oyster shells, and even those rare gems called kidney stones that come from the galaxies of innerspace--and, yes, even those magnificent broke-stones found only in a single planetary system in a galaxy on the very rim of outer space. These latter are practically untouchable, and the more you try to touch them the more broke-stone they become." Zitts drew a deep breath and went on: "If a solitary genius of the latter half of the twentieth century had had the godlike stature to create a work with only one murder in it, instead of dozens, he would be immortal and today worshipped by the protagonists of moderation and hated by the antagonists who maintain, and not without reason, that all of the characters in such stories, and especially the detective, should come to a violent and horrible end on page three." The blonde woman wiped her eyes, glanced into a small mirror and tried to compose herself. "Very well," she murmured half to herself. "I shall prepare myself to endure whatever I must and view as many murders as necessary." "It won't be bad at all," Zitts assured her with feeling. "May even be boring, with so few murders. Personally, I rarely take a case which doesn't offer the prospect of at least a hundred. They generally murder my suspects one after another, and for that reason I try to suspect as many as possible to keep the case interesting. "Now, if you are prepared--" The woman, fearful but dry-eyed, nodded in response. "Pupsie! On your mark! Zoo! Switch on the machine." In fear and wonderment the woman watched Pupsie don the longsnozzle which appeared to be a mechanical nose two-feet in length with its other measurements in proportion. This extra nose did not appear heavy or to handicap Pupsie in any way. Its nostrils flared and the Venusian girl produced some six square yards of white linen, held it significantly at the proper place, and the beast blew its extra nose, making a honking sound which made the windows rattle. "That clears the way for smelling action," Zoo said in explanation. * * * * *
