A BBC Radio 4 full-cast dramatisation starring Peter Sallis as the great Belgian detective. Tyrannical millionaire Simeon Lee has been estranged from most of his family for years. But now, on Christmas Eve, the old man calls them all together once more. Unable to disobey, the children gather uneasily and wonder what their father's intentions are. Does he want to clear up past misunderstandings or cause fresh mischief?
Before they can find out, a deafening crash is heard overhead. Rushing upstairs, they discover a shocking sight: Simeon Lee is lying in a pool of blood, his throat cut. But it is the strangest thing - the door has been locked from the inside and there is no trace of the murderer.
