Years after a fatal plane crash, the investigation is reopened when a missing body is discovered.

It was a tragedy that shocked the nearby Pennine communities to the core. Several deaths were recorded, but one body was never found. That changes when a mountain rescue team, on a mission to help an injured hill walker, stumbles upon a corpse still strapped into an airplane seat.

But something is not quite right. Is the body they found really the missing passenger? DCI Jack Harris feels obliged to launch a new inquiry into the crash. Few people want old wounds reopened, least of all the widow of the pilot and the original investigating officer.

Foul play had been ruled out in the initial findings. Now Harris is not so sure. But a flurry of activity – financial and criminal – kicks off once the news became national. Someone is hiding something, and they are clearly prepared to kill to cover their tracks.

Can Harris crack the mystery and return to his blissful walks in the hills in peace? Or will his meddling in closed cases annoy the powers that be so much that he finally gets the boot?

ERROR OF JUDGEMENT is a standalone in a series of six books featuring the veteran nature-loving detective, DCI Jack Harris.

Readable but nit memorable

This was quite a nice easy read in the series. Since it appears that the order of books is mixed up I would say this should be book 2 as Archie the dog is mentioned as recently acquired and if you have been reading them this far you will know that prior to the end of,and during 'book 3' there was one dog, despite books 1and 2 including 2 dogs. How an author mis-numbers his books I do not know.
Also the blurb of cold case ignites a gripping murder mystery? You don't know anything about a cold case until virtually the end of the book and once again I would hardly say gripping is the correct description. I haven't found any of them 'gripping'. Easy read yes. Fairly short yes. Gripping no. Cup of tea with a biscuit and your feet up I would describe these books as. Readable but not memorable.

Really liked this book. Nice tidy simple language. Story told well and clearly and in stages, so one part of the mystery is set up and just as you think, ok we've solved that, new questions emerge and the story progresses...very well put together. I will go and have a look at some other Jack Harris editions. Good stuff.

Not too bad a read!

Having read all the previous books in the Jack Harris series, this is possibly the most far fetched of reading so far. Some of the passages are repeated word for word, describing different characters that I have a feeling they are cut and paste from each story. I continue reading each of the books to the end, because the story is sufficiently interesting to arouse the need to find out how it ends.....but it is all just a little formulaic and repetitive.
It is a little difficult to accept that DCI Jack Harris has a best friend who manages to feed him information...in every book....from GMP simply because Graham Leckie is in the information gathering section of the police....but is only a lowly Police Constable....he should be at least a sergeant to have the access and be available to attend operational activities within Greater Manchester.
Just so many little things that irritate me that really stop me from actually feeling the book is worth four stars....but it is worth more than three, because it has the “want to know what happened” value.

Cold case skeleton and the chain of events leading to murder

DCI Jack Harris and DS Marty Gallagher pursue a new lead in a twenty-year-old cold case after a skeleton is found under suspicious circumstances. The cold case isn’t what it seems, and when DCI Harris begins investigating, a woman is killed in what appears to be a botched robbery. DCI Harris has doubts.

This is a light, quick read with a well-plotted storyline, with some nice twists. The characters are varied and distinctive—especially the tetchy Harris and Gallagher, who talks in cultural references.

The ending was . . . satisfying except for a hanging thread, which should have been clipped.

I had taken a break from DCI Jack Harris after book #5, but I'm glad I returned. This case reopens old wounds that have festered for 20 years after a plane crash that killed 14 people and ruined the lives and reputations of others. A complex web of bribery and fraud fuels the new efforts to cover up what really happened, and the perpetrators almost succeed until Harris and his local team join forces with others from Manchester. I like Dean's mysteries because they are short and focused. There is some banter and comments about police officers' personal lives, but the attention to solving cases is paramount

Harris, Dog and Bone

I enjoyed this DCI Jack Harris book by John Dean. On a hillside rescue of a young couple, a body sat in an aeroplane seat is discovered. Jack was a young DC when a plane crashed on the hillside, so he remembered the case. Now, he has to establish who the body is. What follows is a trail of unbelievable crime, fraud, blackmail and ultimately Murder. As ever, Jack Harris is desperate to find the culprits. Good read with some great characters, some of which are immensely likeable and some not.

As a reader one easily enters the world of DCI Jack Harris and Matty Gallagher, and as this series develops they become like old friends. It's great to revisit them when a new book comes out.

This one is a stonker. There is revenge, suspicion, jealousy and intrigue. Impossible to pick it up without wanting to know how the plot resolves itself.

A great, entertaining read.

Another action filled Jack Harris thriller from John Dean

As Jack and his team of officers investigate a 20 year old tragic air crash out on the cold, wet northern moors, the number of dead raises elsewhere as suspect after suspect is killed before charges can be laid, is there a mole in Jack's team?

This was another British crime mystery, where Harris and his team investigate an old event about a plane crash.

There were plenty of twists and turns in addiction to highlighting the terrible things people will do to further their own agenda.

Well-written (despite some typos) with realistic characters and sense of place.

Engaging and enjoyable. '

Good Read

When I can't put a book down no matter the hour, it's a book worth reading. Full of intrigue and suspense. DCI Harris has instinct and a calculating way of getting to the bottom line.

An easy read and an interesting story line. Not the gripping page-turner I was expecting based on the cover blurb and some of the reviews, but engaging enough to keep my interest during a long airport layover.
