Verified killers

Bill Mitchell · Leonard Pike · Dorothea Pike

Bill Mitchell killed Carla Constanza, Anna Santarosa and Dr Aycott. Leonard Pike committed the three historical Strangler's Wood murders; his mother Dorothea then killed him after the new investigation exposed what he had done.

Verified motive

Bill killed Carla to stop her terminal smoking-related illness destroying Monarch Tobacco, Anna after she tried to blackmail him with Carla's message, and Dr Aycott to erase Carla's medical evidence. Leonard's earlier killings were sexually motivated; Dorothea killed Leonard after learning he was the original strangler.

Verified important clue

Archive case 7 · checked 16 September 2026Carla Constanza's recorded message

The message preserves Carla's warning after her death and links Anna's attempted blackmail and Dr Aycott's medical evidence to the threat facing Monarch Tobacco.

Clue source: episode transcript ↗

Verified decisive clue

Archive case 7 · checked 17 September 2026Bill Mitchell's knowledge that Dr Aycott was a man

When police deliberately use the wrong name, Mitchell denies knowing 'him' even though they have not disclosed the doctor's sex. The unprompted pronoun shows prior knowledge of Aycott, whose medical records Mitchell needed to destroy, and gives away the person behind the present-day killings.

Verified red herring

Archive case 7 · checked 17 September 2026A revival of the original Strangler's Wood killings

Carla is strangled and left in the same wood as three earlier victims, making a returned serial killer an immediate possibility. The resolution separates the crimes: Leonard Pike committed the historical killings, while Bill Mitchell's present sequence conceals Carla's diagnosis and its threat to Monarch Tobacco.
