Benedict Cumberbatch, Mark Gatiss and Steven Moffat will take part in a special Sherlock convention in April.

They’re among the guests due at Sherlocked which will take place at London’s Excel from April 24-26.

Other guests due attend include producer Sue Virtue and production designer Arwel Jones – organisers are promising more to be announced.

Sherlocked will feature talks, activities and autograph signings themed around the show. It won’t be cheap though, tickets start at £29 and go up to £2995 for a VIP pass. If you want a photo with Benedict, it’ll set you back £595.
