Well, well, well. If you want a book that is full of mystery, threat and chemistry (of both the scientific and romantic kind) then look no further. Poison Garden delivers on all fronts and is, as any fan of the series can attest, another absolute belter of a novel. If there is one warning I would give, it is that to enjoy this book the most you need to have read its predecessor at the very least, but the whole of the series would be your best bet. There are old rivalries at play here, and things from the teams past have a real bearing on everything that comes to pass in this book. That and there would be more than the odd spoiler for cases past if you try and pick up in the midst of this particular misadventure.
Now, for the very reason I would advise you read Death Rocks first, it is very hard to actually review this book without risking the odd spoiler, (unless you've read the blurb of course ...) but I shall try my best. There was a pretty cataclysmic event at the end of Death Rocks which has significant impact upon the course the story takes. But this is not the sole focus of the investigations undertaken. The team is faced with a pair of poisonings, two initially random seeming events which are soon linked and which take Jack Lowerson and series newbie, Charlie Reed, to Alnwick Garden's 'Poison Garden' to try and help them understand the potential origins of the poisons and whether or not it might have been possible for the perpetrator to have taken their samples from the garden itself. Now in a series that is as known for its banter as its crime, it leads to a moment or two of chuckles, much needed in such a perplexing set of circumstances. Having visited the gardens myself on a couple of occasions it certainly made me smile.
There is another element of this book which is carefully woven into the main story. This is a particularly harrowing case from several years earlier, which will have an emotional impact for many, readers included, and acts as a kind of foreshadowing of what is yet to come. We are led through the tragedy that follows and the heart breaking way if affects those who are left to deal with its aftermath. How these scenes were to direct the action in the present day may appear obvious to some to begin with but, as ever, nothing is quite as straightforward in DCI Ryan's world, and how the story plays out may well surprise you. The story is packed with mystery and misdirection, and I found that whilst it kind of led where I expected, the why was perhaps easier to deduce than the who.
For me, the camaraderie and humour in these books are part of what makes the series so addictive, and has me returning to it again and again. There is plenty of banter amongst the team, and a wonderful balance between this light humour and the darker elements of the crimes themselves. Death by poison is no laughing matter after all, and the opening scene is really quite dark by series standards. But LJ Ross takes such care in creating lovable characters in her investigative team that is is impossible not to be totally invested in their fates, and in the outcome of their investigations, no matter how irksome or, potentially, unlikable some of the other characters or victims might be. all of our old faithfuls are here, but the author is not above pointing the finger of suspicion their way when the time comes, making you question, just a little, whether I knew them all as well as I thought. And I am really starting to like Reed and the spark that has quickly developed between her and Lowerson, although it is safe to say that the ending to this book has the potential to set the cat amongst the pigeons. Not a cliffhanger as such, but still...
If you love the series you are going to tear through this one. I think perhaps one of my favourites and heartily recommended.
