To countless women, Amelia Dyer offered salvation: She was a supposedly married but barren woman who offered to adopt babies whose parents (usually unwed mothers) couldn't afford to raise them properly. Dyer promised to rear the "precious" babies as her own and even offered the biological mothers the chance to visit and stay part of the children's lives -- for a small fee, of course. Eventually, one body surfaced that could be tied to Dyer, and then another. Soon, police realized that Dyer had been running a so-called baby farm, killing dozens of helpless children over a span of decades before her undoing.
