The Flower Mill CCTV footage

The Flower Mill CCTV footage is an investigative record of the day Tony Curran was murdered. Its crucial detail is simple but consequential: Peter Mercer is visible behind the counter of his flower shop, providing evidence that weighs against his involvement in the killing.

Discovery and Use in the Inquiry

To satisfy Elizabeth’s curiosity, Peter takes her to The Flower Mill and shows her the recording from the day of the murder. The footage gives their discussion a concrete point of reference: rather than relying only on Peter’s account, Elizabeth can see him at work in the shop. The scene turns a question about his whereabouts into an evidentiary check.

What the Footage Establishes

Peter is clearly visible behind the till. Joyce treats this as ruling him out as the person who killed Tony, and the recording shifts attention away from the flower-shop owner. Its significance lies in this ordinary image of him at work, which serves as an alibi against suspicion; the evidence does not show the murder itself.

Peter’s Alternative Theory

After showing Elizabeth the recording, Peter remains sure that Gianni Gunduz killed Tony. He proposes a chain of grievances: Tony had betrayed Gianni to the police, while Gianni had also stolen from Tony. This is Peter’s interpretation, not something the CCTV independently proves. The footage narrows suspicion by supporting Peter’s absence from the crime, while the proposed motive points the inquiry toward another suspect.
