The Detonators: A Matt Helm Novel by Donald Hamilton
Matt Helm's history with women isn't as good as he'd hoped. They give him a hard time when he's dating them, and now Amy Bartlett is proving too prim and proper for their own good after her father is about to spend time in jail for drugs offences - she wants to set him free, but Matt wants the whole story and doesn't buy the fact she says she's prim - she must have some vices, surely.
