Holby City actor Guy Henry who portrays CEO Henrik Hannsen, is to appear in The Moonstone as Mr Murthwaite.

The charismatic Franklin Blake realises he can only win the heart of his true love, the beautiful and independent Rachel Verinder, if he finds the thief.

He persuades the celebrated detective Sergeant Cuff out of retirement to assist him in investigating the theft and, with the help of the Verinder family’s trusted servant Gabriel Betteredge, they travel between London and Yorkshire in their quest.

Full of cliffhangers, tragedy and intrigue, The Moonstone is the perfect treat for BBC One Daytime viewers.

Wilkie Collins’ famous book not only created the template for Agatha Christie and all who came after, it invented the modern detective mystery novel.
