Some months back, I mentioned the fact that my husband was heading to Leeds to be involved with the making of a TV programme about a murder in his home city back in 1926.   This was after he wrote about the case of Louie Calvert in his book  Murder in  Mind. 

Although he filmed a couple of segments with the company - who were making the programme, Murder, Mystery and My Family- sadly, his contributions ended up on the floor of the cutting room. 
But he did alert the producers to the case, and introduced them to Louie Calvert's great-niece who is at the centre of the programme. So he was very much a consultant even if he never appeared on screen. I promised that I would let people know when the programme is actually going out - so for anyone interested - Murder Mystery and My Family, Episode 10 is on BBC One tomorrow morning at 9.15am
