Kissing the Demons

Thirteen Torland Place is a house with a disturbing past
. When a student living there is found murdered, DI Joe Plantagenet wonders whether her death has anything to do with its grim history. Then other, similar deaths come to light and he fears that a ruthless serial killer is at work.
Could the deaths be connected to Obediah Shrowton, an executed murderer whose presence still seems to linger in the house? Or is there a yet more sinister and dangerous explanation?
