Dangerous Practice — Clare Curzon

Lucy Sedgwick cannot resist investigating a mystery, but finds that crime after crime follows inexorably on its heels. The period is just after the First World War. Psychiatry is in its infancy. Lucy Sedgwick is perhaps a little unwise to rush into another wedding so soon after the failure of her first marriage. But she couldn't have anticipated just how unwise. It is actually during the wedding breakfast that her husband, Clive, is called to London to attend to a patient. Patrick Garston has attempted suicide and Clive must be there when he wakes up. Clive's working life turns out to leave very little time for Lucy, let alone a honeymoon, so Lucy decides to take an interest in Clive's rather alarming psychoanalytical therapies. When she examines the rope that Garston had used to try to kill himself, Lucy realises that there's something strange about the way it has been tied. It was tied by someone left-handed, but Garston is right-handed.
