"When you find that murderer," he said, temporizing, "I shall order you a special nine-foot bone from one of those Martian tyrannasauraplexus creatures. Now, keep your mind on your work!"
At the mention of a tyrannasauraplexus bone Pupsie's jaws slavered and a look of rapture came over his ungainly features. Clearly he had been reformed.
Setting to work immediately, Pupsie sniffed and tuned by twisting the dials, and suddenly the blonde woman gasped and almost fainted.
"That's my lover's apartment," she said in horror. "I recognize the bed. Surely he can't be the murderer."
"Your ex-lover," Zitts pointed out. "That's a corpse in the bed."
The blonde woman fainted, for it was true. The man was dead, or should have been, for he neither breathed nor gave any sign of heartbeat.
"Examine that room," Zitts ordered Pupsie, "until you get a whiff of the second murderer."
Soon Pupsie was off again, sniffing and tuning, and just as another scene came in the blonde woman opened her eyes, gasped, "Another of my lovers," and fainted again.
"Ex-lover," Zitts corrected and directed Pupsie to pursue this murderer also.
They ran through three more murders before the woman recovered, and Zitts deducted, which subsequently proved correct, that these were also ex-lovers. Then, as the woman recovered and was composing herself and straightening her mouth and re-making her face, they came upon a scene with a live person in it.
