The following is an extract from Without Trace, written as Katherine John and published by Random House, paperback Headline,  St Martin’s Press, USA, as Beze Stopy in Czech


“The landscape behind remained unchanged except for a darkly wet slick of gore that slimed off the road into the undergrowth.  The gleam of gold on the eastern horizon intensified, lightening the sky to a translucent shade of opal.  Rain began to fall.  Slight at first it became a downpour as the morning progressed.  A heavy cleansing rain that washed away the traces of blood and flesh, diluting the red stain to a mark that might have been caused by anything.  Cars arrived and sped past in the traffic lanes.  Intermittent at first, they became a steady trickle that roared into a torrent with the advent of the rush hour.  The travellers who glanced casually out of their car windows never thought or wondered at the stain that marred the gravel on the hard shoulder.  But then they were the lucky ones.  For them journey’s end was not yet in sight.”

Midnight Murders – Book Two in the Trevor Joseph series

Compton Castle is a Victorian psychiatric hospital long overdue for demolition. Its warrens of rooms and acres of grounds, originally designed as a sanctuary for the mentally ill, now provide the ideal stalking ground for a serial killer.

Physically and mentally battered after his last case (Without Trace), Sergeant Trevor Joseph is a temporary inmate—but the hospital loses all therapeutic benefit when a corpse is dug out of a flowerbed. Then more bodies are found; young, female and all linked to the hospital. Everyone within the mouldering walls is in danger while a highly unpredictable malevolence remains at large. And, as patients and staff are interrogated by the police, the apparently motiveless killer watches and waits for the opportunity to strike again…

Well written and exciting, this is what a thriller should be. I read the last couple of hours in one sitting- I had to find out who did it and was surprised by the ending.

The Destruction of Evidence – Book Five in the Trevor Joseph series click on jacket for Amazon page #ad

No evidence remained on the corpses of Alun Pitcher, a well-liked, wealthy, careful and cautious businessman and his family after they’d been wrapped in brown paper and string, doused in petrol and ignited. The fires had destroyed all forensic evidence, or so the pathologist and local police believe. Faced with an impossible task, the local force admit defeat and ask for outside help. Following their success in solving a previous “cold'” case, Inspector Trevor Joseph and Sergeant Peter Collins are called in.

Do the murderer or murderers possess knowledge of investigative forensics that have resulted in the perfect crime? Why would anyone want to kill popular family who had no known enemies? How did the killer or killers overcome three grown men and a woman without anyone seeing anything, or hearing a sound? And – has all the evidence really been destroyed?

A Well-Deserved Murder – Book Six in the Trevor Joseph series    – click on jacket for Amazon page #ad

There will always be neighbours from hell. Some deserve to die, but most people stop short of murder. But when Sergeant Peter Collins sees Kacy Howell’s axe-battered corpse, he asks himself if his cousin, Alan Piper, didn’t. Journalist, Alan frequently complained about his neighbours who built a deck overlooking his patio and monitored his every movement. Under cover of darkness they stole his plants and building materials. When his gate disappeared he called in the police who advised him to put up a CCTV camera. Alan had a better idea. Civil servant Kacy Howell is amazed to suddenly find herself the centre of attention at work and showered with unprompted gifts of flowers, and discreetly wrapped sex toys. Her husband, George, is bewildered when a colleague shows him a pornographic magazine featuring Kacy, and then Kacy is found battered to death on the decking that overlooks Alan’s garden. Inspector Trevor Joseph and Sergeant Peter Collins find themselves looking for the perpetrator of a murder, which Kacy’s neighbours have already Christened ‘justifiable homocide’.

Kacy Howells is a seriously unpleasant woman. She bullies her husband, palms her children off on her parents and harrasses her neighbours. When her naked, bludgeoned body is found on the patio at the back of her house there are as many suspects as there are motives. Unfortunately for D.S Peter Collins one of these suspects turns out to be his cousin, journalist Alan Piper who had the misfortune of living next door to the victim with whom he had a long running feud. Peter is taken off the case but his superior and friend D.I Trevor Joseph knows that he will continue to investigate in his own time. He therefore has to work the case at the same time as trying to keep his friend out of trouble.
I really enjoyed this story and thought the identity of the murderer was extremely clever. I love the way the author merges the police case with the personal lives of the main characters. I look forward to the next in the series.

Against advice they struggle to find the evidence they need to prove or disprove the sickening rumours.
