Dandy Gilver, her husband back from the War, and her children off at school is bored to a whimper in the spring of 1923 and a little light snooping seems like harmless fun.

Perhaps the time has come for contemporary Scottish crime fiction to lighten up. Tartan noir has reigned unopposed for too long. Tartan tweed might give it a run for its dirty money.
