Sad but true, one of my smuggest historico-moments was finding the apparently lost grave of the Marr family in the graveyard of St George’s in the East; they were among the victims of the Ratcliffe Highway Murders of 1811.

I took this pic and will let David Bingham, on his wonderful The London Dead website, tell the rest of the story here: http://thelondondead.blogspot.co.uk/2014/06/the-ratcliffe-highway-murders-1-marr.html

One of my favourite true crime books (it makes my top 3 in fact) is The Maul and the Pear Tree, co-authored by PD James and TA Critchley (1971, reissued 2010), which provides a fantastic solution to the mystery.
