When Mortimer Tregennis is found dead under the same terrifying conditions as his siblings, Holmes realises the case is far from over. A strange substance, a smoking lamp, and a private experiment lead him to the truth—but at a terrible cost. And as the final pieces fall into place, Holmes is forced to choose between justice and the law.
