With old-world charm and a military air, Mortimer Rothermere makes a most convincing conman. Just now he is employed by the Cultox corporation, to ensure that no breath of scandal taints the reputation of their successful pet food company near Flaxborough, as the acrimonious marriage of its unsavoury MD, David Harton and his wife Julia, threatens to boil over. But even Mortimer’s habitual sang-froid deserts him in the face of ruthless villainy and actual murder – what a relief that an old friend lives nearby, the incomparable Miss Lucy Teatime, and she is willing to dig out the dark secrets of canned WOOF (with turkey), ‘the caviar of the canine world’.
