David Cartwright

Who they are

River’s grandfather, known throughout as the O.B. — “old bastard”. A retired officer senior enough that his word kept River Cartwright in the Service after King’s Cross, and senior enough that Jackson Lamb answers to something he did at the O.B.’s behest.

He lives in Tonbridge. Glenmorangie, a study, a pasta bake, and a habit of answering questions with aphorisms that sound like tradecraft and may only be fatigue.

What they want

To keep his grandson in the world he himself survived, and to stop him going off reservation. He is honest about the second and evasive about the first.

Book 1 — Slow Horses

• C00 — Present only as the voice in River’s head during the King’s Cross exercise.
• C03 — Over whisky, describes Robert Hobden as a spent force and warns that Hobden was not excommunicated for his beliefs but for airing them; the company he kept before his fall was worse than what followed.
• C08 — Recalled in the hospital; he nearly named River Wolfgang.
• C17 — Named as the man who sanctioned the killing of Charles Partner.

Book 2 — Dead Lions

• C03 — Takes Lamb’s poison theory seriously, names Litvinenko, and identifies the dead man as Richard Bough — Dickie Bow, who vanished in Berlin in September 1989 and came back with a story.
• C03 — Explains Alexander Popov as a bogeyman invented to send Western services chasing a network that never existed, and ZT/53235 as a town that vanished after a plutonium accident.
• C03 — Alone with the dying fire, hears himself give the town’s number digit-perfect and cannot dismiss the possibility that Popov was real after all.
• C16 — Left offstage while River Cartwright wonders whether the O.B. was the officer who framed ZT/53235 in 1951, at the age his grandson is now.

His one conversation in this book is a warning that reads, on the way back, as close to a confession: the man who claims to mislay details recites the only one that matters.

Book 4 — Spook Street

• C01 — At eighty-four in Kent, ties his tie and fixes the date as 4 January — the habit of knowing where and when he is — then loses the thread, walks to the village in his pyjama trousers, and reads a dark neighbours’ house and a flickering streetlamp as surveillance. He insists he is “not quite defenceless”.
• C02 — Refuses to accept that the man at the door is River Cartwright and tests him with his grandmother’s name; decides the answer proves nothing, since any fool can do research, lets the “impostor” in, agrees to a bath, and goes to fetch something from the study first.
• C03 — Not on the page: Emma Flyte walks Lamb round a bathroom on his staircase where an intruder has been shot twice in the face, and David is gone — panic button traced to the kitchen table, gun missing with him.
• C05 — Asleep in Catherine’s flat and deliberately woken by Lamb so the sequence can be tested; the shooting is reconstructed — he shot the man who came for him in his own bathroom, and River then fired a second round into the corpse and left his own ID in the dead man’s pocket. He calls Catherine “Rose”.
• C06 — Kept in Catherine Standish’s bedroom, believing he once lived in her flat; denies having a daughter until she tells him Isobel is his, recites six of the seven dwarfs, and is moved to the neighbour Deirdre’s before Flyte searches the room.
• C09 — Sitting in Moira Tregorian’s office, surfaces at the word “cuckoo” and agrees to talk: eight men at Les Arbres, the ex-KGB Yevgeny, the American Frank in charge, his own debriefings of Henry, and the admission that he had wanted First Desk.
• C11 — Questioned in Lamb’s office with the chair placed centrally and the lamps moved so the light falls round him rather than on him. He names Frank Harkness, says Frank came to his Bayswater house at the end of summer, and when Lamb presses him on what Frank had on him says “Isobel” and weeps.
• C13 — Upstairs with Moira through the gunfight, naming knights — Tristan, Bors, Gareth — and telling her they all started with such promise and all went the same way in the end.

The book’s most decorated memory is also its least reliable: everything it needs from him, it gets by saying “cuckoo” and “Isobel”.

Tells

MCMXIV. The refusal to say “yes” when “probably” will keep him deniable. He is the book’s model of institutional memory: nothing is forgotten, nothing is written down.

Open questions

What exactly he authorised, and what he knows about Lamb’s part in it. His two appearances are both warnings; neither is a confession.
