Former Hollyoaks actor James Sutton arrives in Emmerdale next week as Mark Wylde's (Maxwell Caulfield) secret son Ryan Lamb.

With his mother Faye (Kim Thomson) still married to Mark - the man who she believed to be dead for the past 27 years - she stuns him into silence with the news that she gave birth to Ryan quite soon after he disappeared.

As Ryan arrives in the Dales to stay with his mother, Mark's past is beginning to catch up with him at an alarming pace. Little does Ryan know, however, that Mark is his father.

How long will the truth remain a secret?
