Ordinary thunderstorms can sometimes turn into violent and destructive super-cell storms. William Boyd runs with this metaphor in Ordinary Thunderstorms, his thinking-man's thriller from 2010.
Adam Kindred, a climatologist in London for a job interview, has a casual restaurant conversation with another scientist, a drug researcher. When Philip Wang departs he leaves behind a file, which Adam finds. It has Wang's address and phone number on it, so Adams calls him and offers to drop the file off at his place. This minor inconvenience is the ordinary thunderstorm.
When he arrives at the flat he finds the door open and Wang with a knife in his chest. He pulls out the knife, Wang dies and just like that Adam finds himself the chief suspect in a murder case, his fingerprints on the murder weapon and his name on the visitor register. But this is now a super-cell thunderstorm, and Adam's even greater danger is that Wang's killer, an ex-soldier called Jonjo, is hiding in the flat and, because of that file, wants to kill Adam, too.
Boyd keeps up the tension in the novel's first few pages, but after that those who make a steady diet of thrillers, with their constant action and murders every other chapter, may get bored with Ordinary Thunderstorms, for the center of this storm is prolonged lull, though hardly an uninteresting one for more discerning readers. The author takes us into the London underground, not the subway system but rather the shadowy world into which countless people disappear each year.
Adam finds it amazingly easy to disappear from view, even in a city that has cameras everywhere. He supports himself by begging in the street, avoids using his real name or his credit cards, grows a beard and, for a time, sleeps outside. Gradually he forms a new identity, gets a job as a hospital porter and begins to probe the mystery of what got Philip Wang murdered.
Some of this may strain belief, as when Adam starts dating a police officer and she falls in love with him without bothering to probe his past even a little bit. Still it is fascinating stuff. The novel ends with the suggestion that, while this particular storm may be over, another one may be just over the horizon.
