If you’re listening to your own copy of The Chimes of Midnight at home, there will be a short interval between parts 2 and 3, so you can swap the CD, turn over the vinyl, or take a comfort break.

If you'll be listening to Chimes for the first time, or just need a reminder, the official synopsis below will give you an idea of what to expect from the spooky tale...

'Twas the night before Christmas, and all through the house not a creature was stirring...

But something must be stirring. Something hidden in the shadows. Something which kills the servants of an old Edwardian mansion in the most brutal and macabre manner possible. Exactly on the chiming of the hour, every hour, as the grandfather clock ticks on towards midnight.

Trapped and afraid, the Doctor and Charley are forced to play detective to murders with no motive, where even the victims don't stay dead. Time is running out.

And time itself might well be the killer...
