It is 1936. Pompey Casmilus lives in London with her beloved Aunt, bothered by the menace of German militarism, bothered too by the humbug wich confronts it, bothered most of all by her hopeless love affair with Freddy, Its ending plunges Pompey into melancholy, six months rest and recuperation are prescribed and 'savage, sick and cross' Pompey goes to Schloss Tilssen on the northern German border, only to fall in with a strange band of conspirators: the plum coloured Mrs Pouncer, the absent minded Colonel Peck and the dashing Major Tom Satterthwaite, whom Pompey comes to love.
