The twenty-sixth instalment of the internationally bestselling DCI Banks series Many Rivers to Cross is an ultra-modern novel. It covers subjects that are brutal and pitiless, and probably not in the experience of a high percentage of its readers, but are very relevant to today's world and perhaps always have been. Robinson's subject matter for his trilogy is easy to regard as being a million miles from our experience, but nevertheless it exists, and it should not exist. Robinson's exposure in a detective book primarily meant to be read for pleasure is a brave move, but works brilliantly well. We have the horror of being involved in the loathing and bestiality of the crimes, and the joy and satisfaction when at least some of them are cornered and their reign of terror has ended. We pay homage to Banks and to Robinson for having pulled this off, and we sleep easier. I look forward to the final book in this brilliant trilogy.
