Asimov at his thinnest, which is pretty thin. The victim, Giles Devore, is an enfant terrible novelist of exaggerated reputation and unlimited egomania as well as repulsive sexual proclivities, found dead in the shower by his former mentor Darius Just after a joint autographing session with a brash savant named Asimov whom Doubleday has hired to do a book called Murder at the ABA. Those with justifiable grievances against the late unlamented include Giles' about-tobe-ex-wife and about-to-be-ex-publishers, plus a couple of well-stacked convention and hotel PR representatives. Only for the most incurable Asimov addicts.
