If you enjoy murder mysteries but aren’t a fan of the more gory, bloody thirsty variety of the genre, you will love Richard Osman’s intelligent but ever so slightly sedate ‘The Thursday Murder Club’. Set in a retirement village, four friends gather once a week (“It was Thursday because there was a two-hour slot free in the Jigsaw Room, between Art History and Conversational French”) to discuss unsolved murder cases. One of the club members, Penny, has recently fallen seriously ill and is no longer unable to attend, so the club has decided to recruit a new member. Joyce is the voice of naivete in the narrative, breathlessly excited about her new adventures. (“I’m afraid I don’t know WTF. I only discovered LOL last week”). The other, more experienced members all bring their own particular set of skills to this most unlikely A-team. They are Elizabeth, who was an intelligence agent before never really quite retiring, Ibrahim, a psychiatrist, and Ron, a trade union leader.

The cynic in me suspects that Osman has had some excellent advice on how to sell books. Rule one must surely be “know your audience”. I haven’t taken the time to look it up, but I am believe the main buyers of murder mystery novels written by television celebrities are senior citizens, and it looks as if Osman has constructed his story with that market in mind. The heroes of his novel are the club members who defy all negative stereotypes about the aged. They are energetic, intelligent, and navigate the modern world with ease. The murder club amateur detectives are always one step ahead of the police and break rules (and laws!) with impunity. Jokes about the challenges of modern technology are kept to a minimum. This adds up to create an immensely likeable story despite some of the more conspicuous evidence of its construction. At 377 pages across 115 chapters the pages slip by quickly, and the contrasting narrative voices and cliff-hanging endings all give the story considerable pace. All these elements make this a very easy novel to read. Is it patronising to suggest that this is all intended to make the book more popular with older readers?

I’m not going to summarise the plot, for the obvious reason of avoiding spoilers, but also because it is quite byzantine. There are lots of red herrings, sub-plots and other diversions which add to the page count but at times felt like padding. The ending won’t come as a massive shock, but I don’t think it is mean to – after a while there are only so many suspects left standing!

Despite some of the media coverage of this novel it is anything but ground breaking in its treatment of the old. Miss Marple is an obvious template for the senior citizen amateur detective, using her age to ensure people under-estimate and overlook her while she doggedly pursues her investigations. Having said that, the setting is original (so far as my limited knowledge of murder mysteries can account for). Osman acknowledges that many people living in a retirement home will either have lost a life-partner, or be in the process of losing them, to dementia or other illnesses. Grief is shown as part of everyday life for this community.

It’s hard to avoid the fact that even the very best murder mysteries are written within a fairly rigid set of conventions. It follows that it is not a criticism of this author to say that his first novel seems to be consciously laying down a template for future novels in the series to follow. Why wouldn’t it? I understand he has already written the sequel to this novel, and I think I can hazard a couple of guesses about what will happen in The Thursday Mystery Club 2. The central structure of a suspicious death being investigated by the club members will of course be retained. I think we will learn a lot more about the back-story of Elizabeth and Ibrahim, two key members of the club who so far we only know little about. There’s a lot more to come there if the history of some of the other residents is anything to go by. I also think one of the club members will die – my money is on retired trade union leader Ron – allowing fresh blood to join the club and new characters to be introduced. I also suspect there will be more explicit romantic complications between the retirement village residents, and that PC Donna De Freitas and her boss, DCI Chris Hudson will return for the next set of murders.

Just as an aside, the attitude to death in this novel is interesting. Of course murder mysteries by their nature need to confront death, and one set in a retirement village probably all the more so. But here two characters take their own lives in quite a casual manner, as if for the old death is less of an issue that it would be for younger characters. That might be the case but it doesn’t really square with the zest for life shown elsewhere in the novel. Some old people might be blasé about death and check out willingly when the time comes, but I suspect many others will fight it to the last – certainly Ron, Elizabeth, Joyce and Ibrahim would.

It’s good to see one of the more thoughtful, intelligent television personalities have success as an author. I await the inevitable television adaptations of his novels with interest.
