it be always satisfy when a detective wrap up a case and the criminal be bring to book . in this case the climax give me even great pleasure . to see the smug grin wipe off the face of abigail mitchell when she realise her victim have leave deathbed testimony which leave no doubt about her guilt be very satisfying . please understand represent while i admire ruth gordon performance and her character really and really irritate me . she be selfish and demand . she get her own way by put on a simpering little girl act which be embarrass in a woman of her age . bad and she have now set herself up a judge and jury and executioner against her dead niece husband . when columbo be get too close she try to unnerve him by manipulate him into make an off the cuff speech to an audience of high class lady . he turn the table perfectly by deliver a very warm and humane speech about the reality of police work . nothing can distract columbo from the pursuit of justice . abby final appeal to his good nature be reject because he have too much self respect not to do his job well . here be one situation you can not squirm out of m mitchell .
