Mary Ann Cotton is considered by many to be England's first female serial killer, with allegations that she used arsenic to poison over twenty people, including her children, mother and husbands in the 1850s, 60s and 70s. But was she really a heartless killer who preyed upon those in her care for money to buy the expensive dresses she loved so much? My guest, Martin Connolly, is author of "Mary Ann Cotton: Dark Angel: Britains First Female Serial Killer." He says the answer isn't as cut and dry as many have come to believe it is, and shares his thoughts with us on this latest episode of Most Notorious.
