Fourteen more poisons. Just because it's fiction doesn’t mean it's all made-up ... Agatha Christie is renowned for her captivating plots and creative ways of killing off ill-fated victims. And what better way to add intrigue to a story than poison? The surreptitious ways they can be administered and the characteristic symptoms they produce make these killer chemicals the ideal method of murder in a ‘whodunit’. Christie perfected the use of poisons in her plots; her deft and varied use of toxic substances is one of her great strengths as a writer. But how is it that some compounds prove so fatal, and in such tiny amounts?

Combining Christie’s murder mysteries, chemical science and true crime, V is for Venom is a celebration of the use of science by the undisputed Queen of Crime.
