Where have all the gargoyles gone? Cambridge's number one supersleuth, Sesame Seade, is back and out to catch a thief! When several ferocious gargoyles go missing from the Cambridge university rooftops, Sesame is soon looking for clues at dangerous and dizzying heights. But there's plenty for her to investigate at ground level too, as a spooky set of footprints, a midnight tsunami of scurrying mice, and a bout of strange behavior from Sesame's cat, Peter Mortimer, all point to even more nefarious activity around town. Can Sesame sort it all out before more gargoyles go AWOL? In this riotous follow-up to Sleuth on Skates, the whole gang — including Mr. Halitosis — is back as Sesame pits her wits against a truly devious burglar and a second troublemaker who's been up to no good—right under Sesame's nose!
