Half Human by Stan McMurtry

Description

Divorcé Fergus Munroe meets the beautiful and intriguing Jenny Merridew at a function.  The two are drawn to each other and soon fall in love and marry. Happiness abounds and they live each day in a state of bliss. They move into a tiny 300-year-old run-down cottage in Kent where, during renovations, Fergus discovers, hidden in a bedroom wall, the diary of a young girl. The diary describes several gruesome murders which took place in the vicinity over 150 years ago.

As more such frightening incidents occur, Jenny starts to become really afraid and decides they should sell the place. However, with a stagnant house market, that is impossible.  Jokingly they give their ghost a name but neither Fergus nor Jenny has any inkling of the true horror that awaits them in that sweet, small cottage in the countryside.

Caught in the crossfire of superstition and dread, Fergus must unravel the mystery behind this strange entity before it devours the very fabric of their existence. With each passing night, the line between reality and nightmare blurs. The battle for the village becomes a race against time, trapping Fergus and his friends as they fight for their lives.
