The Secret Seven are excited to be chosen as extras in a local play, but during the opening performances things go seriously wrong.

Could someone be trying to sabotage? The cast and crew are adamant that a theatre ghost must be causing the mysterious accidents, but the Seven aren't convinced. It's up to the gang and their spaniel Scamper to find out who is really behind the mischief - and why! Set in the same world and time as the original stories by Enid Blyton, both Mystery of the Skull and this fantastic new book satisfyingly extend the series for fans old and new. Both stories are brought to life by Tony Ross's brilliant illustrations throughout.
