The Rod of Asclepius

Lady Felicia's reckless driving lands her and Mrs McCarthy in adjoining hospital beds. A new admittance to the ward dies the following morning on the operating table. A nurse claims it is murder and is found dead the same afternoon, forcing Inspector Mallory to do more than his initial cursory investigation. Father Brown, once Sid makes it past the officious substitute Parish Secretary and notifies him of developments, follows a different line of inquiry and Lady Felicia and Mrs McCarthy's snooping put the latter in danger on the same operating table.
