Another episode in Channel 4's true crime series Catching a Killer. Don't worry if you missed the first one a month ago, each episode is a different story.
In April last year, 42-year-old antique book dealer Adrian Greenwood was found dead in his home, having been stabbed more than 30 times in a frenzied and brutal attack. There was no sign of a forced entry, no suspects, and no witnesses, while the only item taken was an early edition of The Wind in the Willows, worth £50,000.
This documentary will let you follow the case from the beginning, getting fly-on-the-wall access to the work of the Thames Valley Police Major Crime Unit as Det Supt Kevin Brown and his team embark on their investigation into who killed Greenwood, and why.
