One poisoning on the list:
A Series of Unfortunate Events by Lemony SnicketRead about the other poisonings on Mullan's list.
In The Reptile Room (the second volume of this thoroughly Gothic children's roman fleuve) Uncle Monty, a keen herpetologist, appears to have been killed by a bite from one of his own snakes. In fact the benevolent guardian of the Baudelaire orphans has been poisoned by the fiendish Count Olaf, who is after the Baudelaire inheritance.
See what Lemony Snicket was reading a few years ago.
