Pairing a rhymed text to digitally colored “Spy-vs.-Spy” style cartoons, Rash sends a secret agent out on a quest to find the ringer among his 25 associates. Agents on the up and up are linked to a same-letter device or action: “Agent M has got a solar / Microphone inside his molar”; “Agent W attacks / a spy she didn’t know was Wax.” Eventually, Agent A concludes that he must be the culprit, but he’s quickly exonerated for having found the Answer, and joins all the other men (and women) in black for a group boogie. Chicka Chicka Boom Boom this isn’t, but some of the rhymes are clever, and there’s a movie in miniature, or at least a familiar scenario, on nearly every page. (Picture book. 7-8)
