Vera: The Moth Catcher

DCI Stanhope and her team, including new recruit DC Hicham Cherradi, travel to a remote country house when the woman looking after it is killed. No sooner have they arrived, than a second body is discovered. Vera discovers the two victims met the night before their deaths, and goes in search of a connection between them. Forensics evidence reveals that one was definitely present when the other died - but when no murder weapon or motive can be found, Vera begins to suspect a third party was involved
