Where have all the gargoyles gone? Supersleuth Sesame Seade is on her second case the minute she learns that several of the monstrous stony sentinels on the Cambridge University rooftops have gone missing. But as she courageously tracks down clues—some of which lead her to dizzying heights—and starts piecing them together, she realizes that gargoyles gone AWOL isn't the only mystery afoot in town. From peculiar footprints on the lawns and torrents of laboratory mice running wild to the strange lethargy of Peter Mortimer, Sesame's normally ferocious cat, Cambridge's number-one supersleuth suddenly has her hands full. In this riotous sequel to <i>Sleuth on Skates</i>, the whole gang—including Mr. Halitosis—is back as Sesame pits her wits against a devious gargoyle thief <i>and</i> whoever is behind a spate of strange scientific experimentation!
