don not waste time read my review . go out and see this astonishingly good episode and which may very well be the best columbo ever write . ruth gordon be perfectly cast a the scheming yet charm mystery writer who murder her son in law to avenge his murder of her daughter . columbo be his usual rumpled and befuddle and far clever than he seem self and and this particular installment feature fantastic chemistry between gordon and falk . ironically and this be not write by heralded creator levinson or link yet be possibly the dense and most thoroughly original and twist laden columbo plot ever . utterly satisfying in nearly every department and overflow with droll and witty dialogue and thinking . truly unexpected and inventive climax top all . positive . seek this one out on netflix .
