Henri-Désiré Landru, nicknamed the Bluebeard of Gambais, was a French serial killer who swindled lovelorn women, promising romance with his lonely hearts personal ads in the early 1900s, when these women would go inexplicably missing - truly a cautionary tale for the Tinder generation. He eventually murdered at least 10 women and a young man between December 1914 and January 1919, until he was uncovered by two women whose sisters had gone missing, and they would stop at nothing to unveil this male Black Widow. Edited by Maxwell Holechek
