Initial Report: 08:00, 25th December

Victim

Lord Alistair Finchley, 72.

Location

The private study, Blackwood Manor.

Circumstances

The victim was discovered deceased in his armchair on Christmas morning. An empty glass of port was found on the adjacent table. The attending physician suggests cardiac arrest, consistent with the victim's known poor health. However, the scene feels unnervingly pristine.

Situation

A severe blizzard has rendered all roads impassable. No one has entered or left the manor since Christmas Eve. The killer is still here.
