Blackcap

Detective noir meets The Witcher in a post-apocalyptic city reminiscent of Victorian London.
Kade Blackcap was once a famous detective. Overburdened with guilt at sending a man to the noose, he finds himself unable to take a case for fear of the consequences. But with the taxman breathing down his neck, he has to find work soon, or he'll lose the house his father left him.
He has one hope left.
Long has he suspected the myths of old were creeping back into the world, and with his detective background he has all the skills to hunt them. But once he finds himself on the trail of a monster, he realises how out of his depth he is.
He might have the skills to track such a creature, but what will he do when he catches up with it?
