Miskatonic University Medical School, Arkham

A respectable teaching hospital that becomes, case by case, the source of an increasingly well-traveled trail of test subjects. West's later work moves the same experiments to Bolton and to the battlefields of Flanders, but Arkham is where the reagent — and its consequences — began.

Whereabouts: The medical school of Miskatonic University in Arkham, Massachusetts, with a well-appointed dissection room West's research quietly outgrows.

Access: By ordinary enrollment — West and his roommate-narrator are both students there, with laboratory access that makes their after-hours experiments simply a matter of staying late.
