The Customer Has Kept the Ending

A puzzle maker is paid to restore a handmade jigsaw missing its final piece. A print technician identifies a scene that was never photographed, and their search for the customer becomes a race to stop an ordinary pastime being used to rehearse someone else's carefully planned disappearance.

How it begins

The jigsaw showed Frances Cole's workshop from a window that did not exist.

She assembled the last available corner piece and looked up at the blank wall.

In the picture, afternoon light fell across her cutting table. Her red mug stood beside a stack of boards. A man in a dark coat waited near the door, his face occupying the one missing piece.

Frances had received the puzzle that morning with a request to reproduce its final section. The customer enclosed a generous deposit and no photograph.

Stephen Reed arrived to calibrate the print scanner.

'New commission?'

'Old photograph, apparently.'

He studied the puzzle surface.

'That isn't a photograph.'

'It's very good at pretending.'

'Look at the reflections.'

He pointed to her mug. The printed handle cast a shadow toward the light. The error was small, but it made the room feel less like a place than somebody's persuasive idea of one.

Frances checked the customer email. Recreate the missing piece faithfully. Do not improve the scene.

'Could someone have drawn this from the street?'

Stephen went to the door. From outside, the table was hidden by shelving. The red mug had only arrived last week, a gift from a client who apologized for being difficult with a difficult color.

On the puzzle, the clock above the table read four seventeen. It was three fifty-two.

Frances laughed once, without humor.

'We're not waiting to see if he arrives.'

She photographed the puzzle, saved the order details and asked Stephen to stay while she called the customer.

The number rang from inside the parcel's packing box.

A small telephone lay beneath the tissue, already counting down to an alarm.

For the first time, Frances understood that somebody had not sent her an incomplete picture. They had sent a rehearsal and expected her to remain inside the frame.

Outline and characters

Develop this idea

The puzzle's image should be a constructed rendering with a traceable source for its intimate details. Avoid unexplained prediction in an otherwise practical thriller. Frances should act once the timed threat becomes credible rather than remain for spectacle. Research printing and jigsaw production to support Stephen's clue. The adult seeking escape needs a specific lawful problem, and the final solution should distinguish their agency from another party's attempt to profit from a false account.
