The Confessions of Dorian Gray begins with their final encounter in Paris at the dawn of the twentieth century, continuing right through to 2007 and the present day.

Alexander Vlahos (The Indian Doctor, Privates, and soon to make his debut as Mordred in Merlin) will star as the eponymous antihero.

'We couldn't have been luckier in the casting of Alex,' says producer Scott Handcock. 'I've worked with him a few times now, and he's one of the most instinctive and exciting actors I've ever seen in studio. He's a real pleasure to work with and has been wonderfully committed to the project from day one! We have demons, romances, possession, ghosts - you name it! All of which offer fascinating glimpses into the mindset of Dorian Gray. And Alex has most certainly risen to the challenge!'

A series of five half-hour episodes will be available to download weekly from October this year (priced £2.99 each or £12.99 for the series) and has been written by regular Big Finish contributors David Llewellyn, Scott Harrison, Gary Russell, Scott Handcock and Joseph Lidster. A Christmas special will then follow in December.

Fans who want a taste of what's to come can enjoy Alexander's debut as Dorian in the forthcoming Bernice Summerfield story Shades of Gray, available as part of the Legion box set from September.
