Preparations for the Ghastly-Gorm Garden Party and bake-off are under way. Celebrity cooks—such as Nigellina Sugarspoon, Gordon Ramsgate and Heston Harboil—are arriving at the hall for the big event and, true to form, Maltravers, the indoor gamekeeper, is acting suspiciously.

Ada vows to aid the course of true love and find out what Maltravers is up to, but amidst all this activity, everyone, including her father, appears to have forgotten her birthday!
