Meet Serge A. Storms, the lead character in Tim Dorseyslatest title, Nuclear Jellyfish. Serge is a bit of an oddball. Hes a tour guide, history nut and, oh yeah, serial killer. This time Serge is after a diamond thief called Jellyfish, but he doesnt mind putting some hurt on skinheads beating up a homeless guy or motel managers and car mechanics who shortchange the tourists as well. The camp, violent Nuclear Jellyfish isnt the right read for anyone with a weak stomach, but those fans who dont object to bad guys getting their due even when its from other bad guys will love it. Dorsey reads from and signs his 11th thriller today at 6:30 p.m. Murder by the Book, 2342 Bissonnet. For information, call 713-524-8597 or visit www.murderbooks.com. Free.
