Season 4, Episode 3- By Dawn’s Early Light

Colonel Lyle C. Rumford runs a military academy that’s about to be closed down by the founder’s grandson- William Haynes. Rumford’s face is sweaty throughout.
William turns up and insists on presiding over the founder’s day ceremony, Rumford had counted on this and has rigged a canon so that it will back fire and kill him.
Although it looks like an accident Columbo still shows up to sniff around at 16 minutes and 44 seconds. He hangs about outside on all girls school and sets up a rebellious cadet called Springer. The columboid: elusive cider.
Columbo was in the army, wears a vest and size 10 ½ to 11 socks and only his wife uses his first name.
During this episode I ate a giant meringue.
