7pm, Monday 23rd June 2025 – Royal Institution
Agatha Christie revelled in the use of poison to kill off unfortunate victims in her books, using poisons more accurately than any other crime writer. But how is it that some chemicals in such small quantities can be so deadly? And how feasible was it to obtain these chemicals both in Christie’s day, and today?
Join chemist-turned-writer Kathryn Harkup as she explores how Christie’s extensive knowledge of drugs and medicine mixed with real life cases, created her brilliantly plotted crime novels. Her poisons were picked with care to give clues, red-herrings and interesting new twists to her classic crime novels, whilst maintaining scientific accuracy. Kathryn will uncover howdunnit, but whodunnit is still up to you to find out…
Copies of Kathryn’s book “V is for Venom: Agatha Christie’s Chemicals of Death” will be available to purchase after the talk.
