Meanwhile, Tibbles the cat leaves Mrs Clam and Miss Thimble a grisly gift; a human eyeball! Sister Boniface is on the case, whilst Sister Reg grapples with the heartache of having to sacrifice her friend Terry the Turkey for Christmas dinner.As pantomime rehearsals commence Jonas' questionable artistic vision creates hostility within the company, whilst Miranda's hatred of Bunny causes her to snap at the enthusiastic props assistant Wilf.

Can she unmask them before they strike again?
