i love this episode of columbo . maybe it because ruth gordon be in it and she be wonderful a successful mystery writer abigail mitchell and an american version of dame agatha christie . she be delicious to watch a the perky and lovable author who suffer a terrible loss when her niece die in a drowning accident . she blame her niece husband and the nephew . she plan to kill him to avenge her death since the police have abandon her . i would have love somebody else than mariette hartley to play veronica . i never really like hartley in anything personally . and of course with columbo and there be some laugh like when he question veronica at a belly dancing class . ruth abigail be a smart sleuth herself and she match wit with columbo always play wonderfully by peter falk .
