Clare Addison

Who they are

Min Harper’s widow, who rings Slough House in C01 and introduces herself by both her names at once: Clare Addison now, Clare Harper as was. She has two sons, Lucas Harper, seventeen, and Andrew, two years younger. The book gives her no job, no street and no history except the one that matters — she was married to a slow horse who died, and when her son disappears she has nobody else to ask.

Her first move is to ring the dead man’s old desk and reach Louisa Guy, the woman who was sleeping with her husband. She does it knowingly, and says so at the end of their second meeting, in a Soho café, when the request for help has failed.

She is the book’s engine rather than its agent: everything the slow horses do in Wales starts from her missing son. She appears in person only twice, by telephone in C01 and in the café in C02; afterwards she is a voice on Louisa’s phone, supplying browsing history and paperwork, and the owner of a cottage in Pembrokeshire that she and her boys use twice a year.

What they want

Her son found, and to be taken seriously by the Service that employed his father. When Louisa tells her Lucas left of his own accord and will come back, Clare hears the brush-off inside it and turns the affair into an invoice.

Book 6 — Joe Country

• C01 — Rings Min Harper’s old line and identifies herself as Clare Addison, Clare Harper as was; tells Louisa that Min was her husband.
• C02 — Meets Louisa in a Soho café: Lucas, seventeen, gone three days with a few hundred pounds and a small rucksack, having run off before after Min left and died. She mentions Andrew, Lucas’s catering work in Pembrokeshire, and his remark that he was no longer worried about a student loan, and says she feels watched.
• C02 — Accuses Louisa of not caring and leaves: “But you were fucking Min, weren’t you? I’d have hoped that counted for something.”
• C03 — Present in Louisa’s thoughts at the funeral: Min’s widow, frightened by her son’s disappearance.
• C05 — On the phone with Louisa: Lucas left his phone behind but took his Fitbit, and she supplies the browsing history and paperwork that link Paul’s Pantry and Caerwyss Hall.
• C07 — Her cottage, Bryn-y-Wharg, which she and her boys use twice a year, is the address Louisa drives to through the snow.

Tells

The name, offered twice and corrected in the same breath — Addison now, Harper as was. She apologises for being late and then presents the affair as a debt. Her fear is specific and practical: she says she feels watched long before anyone in the book believes her.

Open questions

What she knew about Lucas’s sudden money and about what he saw at the Hall, and whether she is ever told how Emma Flyte died. The chapters leave her at the edge of the story, telephoning.
