“If only the swans would swim side by side on the dark green lake, this picture might turn out to be the crowning achievement of the wedding photographer’s career.”

A national lock down seems like the right time to get through some of the larger hardbacks on my shelf while I haven’t got to be carrying them around. As such, we come at last to the fourth part of the Strike series, Lethal White. It turned out that aside from the last couple of pages and one or two smaller plot points, I had all but entirely forgotten everything that had happened in Career of Evil. Fortunately, you don’t really need to know that much, as very quickly we’re plunged into a brand new case which leaves you almost unable to put the book down. There are also some spoilers ahead for the previous books, so that’s your final warning.

Robin and Matthew have just tied the knot, but within minutes of the vows being said it seems that that knot is strained. When Robin realises that Matthew deleted some messages from Strike from her phone, she loses a great deal of trust and respect for him, but for the sake of their families, they go ahead with the honeymoon. A year later, their marriage isn’t in much a better position, but there are other things to worry about now. Following the high media attention that Strike and Robin received after finding the Shacklewell Ripper, Strike has fewer money worries and can hire some more detectives, but is less able to be covert himself. A problem falls in in his lap, however, when Billy, a mentally disturbed young man, bursts into his office and tells him he once witnessed a murder. Before Strike can find out anymore, Billy bolts in a panic.

Thus the case begins. Using what scant knowledge he has, Strike finds himself going from the very poorest corners of London to the highest echelons, where Jasper Chiswell, the Minister for Culture, has asked him to step in and find out something about Geraint Winn, the husband of the Minister for Sport, who is blackmailing Chiswell. Robin goes undercover in the Houses of Parliament and begins to get to know the Chiswell family and the people around it. Strike meanwhile is keeping tabs on Billy’s brother Jimmy, an anarchist who is currently protesting the damage done to London by the upcoming Olympic Games. When these two cases collide, it spells a fatal end for one of Strike’s clients. He and Robin now need to work out who is keeping secrets, because someone knows more than they’re letting on, and they’re determined to get to the bottom of it.

Rowling, despite her flaws, has always had a knack for characters and really has a good handle on how mysteries should work. It’s been said before, but several of the Potter books are basically just murder mysteries and it’s never been a surprise that she went into crime once she’d finished those. As with all the best mysteries too, it’s all there for you to solve, but I admit I didn’t quite see the ending coming. Rowling excels once more at keeping a complicated and twisted plot together and the book’s length seems almost justified. There’s a stark realism to the books that is thoroughly captivating. It’s also a prolonged study into the class system, showing the working classes being brushed aside and left to struggle, with the wealthy repeatedly showcase their belief that the world is there solely to bend to their will. Divisions are hugely prevalent, as are the themes of pairs and partnerships. Rowling is, really, quite a skilled writer, and becoming increasingly brilliant.

I remain disappointed by the inclusion of the romantic sub-plot, though. I’ve no problem with Robin or Strike being in relationships, as indeed they are, but the constant nods to the fact that they might be falling in love with each other are non-essential. The story works perfectly well without adding in the further tension to their relationship that it might be more than professional. The relationship, nonetheless, feels real and well-painted. As ever with Rowling, the characters are solid and real, each with depth and perfectly-fitting names. Strike is still one of the most interesting detectives of recent years, and Robin is aptly named as his competent sidekick who this time round gains a new strength that we had already seen coming to the forefront. She is determined and forceful and I adore spending time with her.

Another excellent addition to the series. I read this week that Rowling has plans for “at least ten more”. I’m not sure I have space on my bookshelf (or the upper arm strength) for them, but if the quality stays this good, I’ll do my best to try.

Did you know that as well as reviewing everything I read, I also write novels, too? My books blend black humour with light horror, crossing genres with ordinary characters dealing with extraordinary circumstances. Head over to wherever you buy books to take a look at my two offerings. The first, The Atomic Blood-stained Bus, introduces you to a cannibal, an ex-god and the last witches of Britain, while the second, The Third Wheel, follows a man who is tired of being single while all his friends get married, but has a change of priority when aliens invade the planet. I hope you enjoy!
