Gerry Wade had proved himself to be a champion sleeper, so the other houseguests decided to play a practical joke on him. Eight alarm clocks were set to go off, one after the other, starting at 6:30 a.m.

But when morning arrived, one clock was missing and the prank then backfired, with tragic consequences. For Jimmy Thesiger in particular, the words "Seven Dials" were to take on a new and chilling significance...

Join Lady Eileen ‘Bundle’ Brent and friends as they unravel this mystery and discover why a heavy sleeper would die of an overdose of a sleeping draught. Why were there only seven of the eight clocks found, neatly and sinisterly arranged on the mantelpiece? The answers lie within the enigmatic Seven Dials Society.
