Remove the children and welcome back fat Detective Chief Inspector Dover, who has never before been as hilariously foul, rude, stupid, piggish, and unclean as he is in this tricky murder case. The place is posh Frenchy Botham, and the victim is an unidentified teeny-bopper found dead at the gate of one of the fancy houses along ""The Grove."" As long-suffering Sergeant MacGregor watches in horror, Dover accuses and offends everyone in sight, even thinks about framing one of the suspects just to finish the case up quickly, falls asleep during interrogations, and eats to excess everywhere (""the usual 'feeding-time-at-the-zoo' spectacle""). Still, somehow the case gets solved, and rather neatly too--but the high points are purely comic: a visit with a school principal barricaded in his office out of fear of the students. . . and a tot's appropriate baptism of Dover's hat. Another scabrously silly triumph for ""Scotland Yard's most unwanted detective.
