The head of a private military think tank who's been embezzling funds from the institute murders a colleague who's been investigating him, while devising a watertight alibi. Lt. Columbo dismantles his alibi.

A Colonel works for a highly revered and well-respected General. Among the things that he has been doing is having an affair with the invalid General's wife and diverting funds from the General's foundation to fund arms sales. The General discovers some peculiarities going on at the foundation, so he instructs Sergeant Keegan to investigate; he learns of the Colonel's activities, then instead of reporting it to the General, he tries to blackmail the Colonel. The Colonel, in turn, kills the Sergeant, but it's not long until Lt. Columbo is on the case and on the Colonel's trail.—<[email protected]>

A highly respected General engages his Sergeant to investigate some anomalies going on within his foundation. The Sergeant uncovers evidence that Colonel Braille, a brilliant but arrogant man, is diverting foundation funds to weapons sales and tries to blackmail him. Not only that, the Colonel is always having an affair with the General's beautiful young wife. When the Sergeant tries to blackmail Colonel Braille into including him in the diverting of funds, Colonel Braille murders him and tries to establish a perfect alibi, but the dogged Lt. Colombo is on his tail.—charmardee-smith
