On the afternoon of Sunday 1st May 2016, 31 year old Natalie Hemming, mother of three, vanishes seemingly without a trace. 48 hours later her frantic mother phones 999. "What's the specific concern that's caused you to call the police?" says the operator. Her mother replies, "Him".

That phone call launches one of the biggest missing person searches ever seen at Thames Valley Police.

With extraordinary access to the minute by minute police investigation and to Natalie’s family and friends as they struggle to come to terms with the situation that is unfolding around them, Catching a Killer: The Search for Natalie Hemming follows the case from the critical hours before the arrest to its heart-breaking conclusion.
