Surgeons' Hall

Visiting the Great Exhibition to view the wax anatomical models of the famous but reclusive Dr Merlin Strangeway, Jem Flockhart and Will Quartermain find a severed arm, perfectly dissected and laid out amongst the exhibits. Assuming it to be a prank by medical students, they return it to Dr Strangeway, who works at Corvus Hall, a private anatomy school run by Dr James Crowe - one of Edinburgh's most revered surgeons and teachers of anatomy.

Jem's persistence reveals that a body does indeed lie in the school's mortuary, minus its right arm. But the body has no provenance. More macabre still, its face has been dissected, making identification impossible. Dr Strangeway denies all knowledge, and Dr Crowe seems unwilling to pursue the matter.
