Death Ray Butterfly — Tom Lichtenberg

Inspector Stanley Mole doesn't mind a hard case, but things have gotten out of hand. There's a killer who escapes to a parallel universe, a 20,000 year old murder, a witness to her own death, a toddler assassin, subatomic-particle sniffing butterflies, and much, much more. This time it's not just his reputation that's on the line. This time it's more than personal.
