Cliffo and Bronte spoke to Gemma Bath from Mamma Mia's True Crime Conversations about the poisoning of Ethel Griggs in 1927.

After eating supper with her husband Ethel quickly became ill, and just over 48 hours later she was pronounced dead.

When police exhumed her body just two weeks after Ethel was laid to rest, they found enough arsenic inside her stomach to kill not just Ethel, but several people.
