I don’t know how it’s possible, but this series just keeps getting better and better, so much so, I need more than five stars to rate it. The only downside of this latest adventure with former LAPD detective and now cold case worker, Harry Bosch is, because I virtually inhale the book the moment I start it, it’s over far too soon.

In Two Kinds of Truth, Bosch is faced with present and past dilemmas. He might be working on cold cases, but when one of his from 30 years earlier is resurrected, one which not only put a psychopath on death row, but which, if the killer’s appeal to have his sentence overturned and massive compensation paid succeeds, throws every case Harry has ever worked on, every criminal he ever helped convict, into doubt.

Claiming Harry framed him and he has the evidence to prove it, the killer’s case appears tight, so much so, Harry’s former partner is persuaded to help those assigned to investigate the matter. Things look grim for Harry, particularly since he left LAPD under less than salubrious circumstances. Determined to clear his name, he commences his own investigation.

In the meantime, he’s asked to help in a brutal double-murder. Keen to be back on the streets and working “hot”, Harry and his team uncover the corruption and cruelty of big pharma, those who benefit from its nefarious dealings, and the toll this takes on the most vulnerable in society.

Older, most definitely wiser, with the cunning of a fox and instincts of a seasoned hunter, and yet willingness to share his knowledge and experiences, if there’s one thing Harry will not stand for, it’s having his honour – as an officer of the law and man – questioned. Nor will he tolerate the motives of a good person being trashed, especially when they’re no longer there to defend themselves or explain their actions and motives. This means Harry will take terrible risks in order that the truth outs and that those who seek to bury it pay the consequences of their deception.

But Harry is dealing with those who don’t share his values and don’t care about truth – unless its silencing the man who seeks to find and expose it.

Taut, fast-paced, but without sacrificing tension or emotional integrity, this is a magnificent read that is impossible to put down. Characters from previous books such as Lucy Soto, Jerry Edgar, Mickey Haller, Harry’s daughter and others appear, their desire to help the man who has always had their back admirable, though not always successful.

Like all the Bosch books, it can be read as a standalone, but the rewards for following Harry’s career and personal life are so much richer when you have the whole context.

Highly recommended – nah, bugger that. Read it! You won’t be disappointed.
