Farmer John Tatton constantly belittles his rebellious son Alfred, an insufferable knave in town, who dies mingled in a farm machine shortly after standing up threatening with the same. Father Brown finds out Alfred was the lover of GP Adam Crawford's much younger wife Oone, who was probably unsuccessfully hiding her pregnancy. Unlike Inspector Sullivan, Brown mistrusts the anonymous letters declaring Crawford, who had means, the killer, even after a guilty plea and before hearing his confession.
