"Collecting Cooper" is the fifth novel in Paul Cleave's Christchurch noir series and the second novel to feature Theodore Tait. As with all the novels in the series, there are a number of interlaced storylines featuring events and characters from other novels in the series. This quality to the novels creates not only a familiarity but also weaves the series together in a unique manner. "Collecting Cooper" features (as many of the other novels) a serial killer theme and the storyline is quickly developed into a mystery around whether there are one or two serial killers. A thoroughly engaging crime thriller with many twists and turns and a decent reveal.
