Just when Hamish most needs him - the dentist turns up dead...In Scotland, where thrift and a 'nice set of dentures' are generally admired, dental surgeon Dr Frederick Gilchrist's cheap rates and penchant for pulling teeth have gained him a clientele. However, wiser Highlanders (like Hamish Macbeth) opt to steer clear of this reputed womanizer's all-too-busy hands. Only jaw-throbbing agony drives Hamish to Gilchrist's surgery, but what he finds is the dentist's dead body - putting several angry husbands in the frame for murder.
