I really liked this book. First and foremost, it's dark, the London setting adding to this aspect even if it starts in summer; however it culminates in autumn rain which is very fitting. It's genuine suspense. The fiends are believable. The pace sometimes moves on with breathtaking speed, as with Paul's escape from Delta Egypt's office in Cairo, sometimes it just crawls on when Jade and Paul do their research at their desks, just as it is in real life. And also very believable is that Paul's toiling and moiling doesn't make him famous in the end; his tribute to solving the crime, albeit somewhat crucial, is lost beneath the work of the police.
This hero to me is a welcome change from all the superhero - like PI's who people today's bookshelves. He's just doing his job, and he is good at what he does because he is "a natural at finding out things that nobody wants to tell me" as he puts it himself. But he has his issues; starting with the trauma of his childhood, the sins of his youth, his recent mistakes. It was even fun to meet his little mannerisms like his ability to name the exact number of days, hours, and minutes since or until an incident or the rules he sets for himself like his love for whisky which he never drinks before 6 pm. Almost never. Paul is gay, a fact which is important for the plot as it leads Paul to make horribly wrong decisions, but he is not reduced to that single facet of his personality as it is often the case within the genre.However, it's perhaps that fact that allows for a depth of emotionality that would look weird on a "straight, hardboiled PI". When Paul is upset, he cries. When he is in pain, he begs. He can even be so lovesick he makes a fool of himself. Yet, he simply breaks into a building to gather information or to shoot a picture of his client's wife and her lover in a captious situation. He's a three dimensional human being I could feel sympathetic for although I didn't always share his point of view; however, his decisions and actions are completely comprehensible. Even the supportive characters are rendered equally inherently consistent, proof of the author's formidable storytelling.
This mystery/ suspense book is too good to disappear within the confines of "m/m fiction" just because its major character happens to be gay. I strongly recommend it to everyone who likes themselves a good thriller.
