With girlfriend DS Jacquie Carpenter back at work and baby Nolan rapidly growing into a feisty toddler, Peter “Mad Max” Maxwell, Head of Sixth Form at Leightford High, hires an au pair. But one afternoon Max returns home to find that the exotic Juanita seems to have disappeared into thin air. Meanwhile, two walkers are surprised and disturbed when their Border Collie digs up an arm on Dead Man’s Point. Max is no stranger to murder inquiries - but with a creepy gardener, troublesome teenagers and reports of a randy rambler to investigate, an au pair to search for and a baby to look after, Max may have taken on more than he can handle.
