A Fever of the Blood by Oscar de Muriel

A Fever of the Blood (A Case for Frey & Mcgray) - Oscar de Muriel

Murder most foul in an Edinburgh lunatic asylum strikes too close to home for 'Nine-Nails' McGray.
He knows the escaped maniac responsible....a madman who shares a secret with McGray's own sister that he will do anything to uncover.
Even if it means following a bloody trail that leads from Edinburgh to the home of the legendary Lancashire Witches......who may not be as dead and gone as people think.
