YMMV / Midsomer Murders S 14 E 7

• Complete Monster: Matthew Hendred is a smug, boorish man who regularly mistreats his family and is secretly a former mercenary who in his youth fought in a Sub-Saharan war. In 1978, Hendred participated in the attack of an African village where 23 unarmed civilians were massacred. After the war, using the connections he'd developed, Hendred set up a "private security" company, making himself very rich. Blackmailed by a survivor of the massacre, now an elderly nun at Midsomer Priory who wanted him to donate a portion of his fortune to a charity for war victims as penance, Hendred opts to simply silence her. Breaking into the Priory he mistakenly strangles the wrong nun. Then, thinking he also knew the truth, Hendred strangles the local priest, and upon realizing his mistake tried again to kill the nun, willing to murder anybody to hide his Dark Secret.
