Telephone Tip-off

The manager of the The Grand Unblessed Hotel  has phoned the the Anomaly Detective Agency  in the very early hours of the morning. He is stammering, and steps away from the phone multiple times to cough. There has been an accident, an incident, probably a murder at his hotel. One of his guests has been found dead. The room is allegedly 'contaminated with magic' - he refuses to say anymore over the phone. He doesn't want the police  involved, and he wants it sorting with expertise and, more importantly, discretion.
You have arranged to meet at the Grand Unblessed Hotel at 5am.
