Much to my delight this short story by Mick Herron brought together two of my favorite characters from the Slough House series, Jackson Lamb and Molly Doran. Molly has invited Jackson to meet her at St Leonard's church, often called the Spook’s Chapel, where the spies are buried. He comes because he owes her. There she tells him a story that she has unearthed but that Jackson already knows because he is part of it. A background story on Jackson is always welcome, but the twist at the end provides both surprise and insight into who Jackson Lamb is.

Really enjoyed a look back into Lamb when he was behind the wall. I assumed he was part of the story being told, but I figured he was Cross and not the mirror man! Shows that he’s always protected his joes at all costs, even if it led them to hating him and not understanding why he did the things he did. (8.5/10)

Fyrsta smásagan í seríunni sem sneri að aðalkarakterum seríunnar en ekki hliðarkarakterum. Mjög skemmtilegt concept og ótrúlega gaman að fá sögu sem er í raun prequel frá kalda stríðinu. Væri til í heila bók um spook daga Jackson’s. Hún virðist (enn sem komið er) ekki framfleyta megin söguþræðinum neitt og vera bara stutt skemmtileg saga. Mjög ánægð með þessa.

Pretty standard spy story narrated by Molly Doran who's used her wheelchair to block Jackson Lamb in a pew in the Spooks' Chapel at St Leonard's church. Well-told, but not too interesting until the end when Molly gets Lamb to admit to the cold heartedness of his personal rules about "joes". Provides context to some of Lamb's actions in the main Slough House books.

This was a fun short story! I’m so curious to know more about Lamb’s backstory. I loved the twist at the end, and I loved what it shows about Lamb’s character.

Cold, short, and sharp—this story cuts deep. Two old spies talk while the world moves on without them. The past hangs heavy, like wet clothes in winter. Nothing explodes, but everything matters. It’s quiet, sad, and true—the kind of story that stays with you.

Really enjoyed. Love how Mick Herron weaves between the past and current.

He’s quickly become one of my favourite story tellers.

"The Last Dead Letter" is a short story by Mick Herron, included in the anniversary edition of Slow Horses," the first Slough House novel, and despite being a 28-page short, Herron packs this glimpse of Jackson Lamb's past with enough misdirection and mystery to satisfy

Very nice. This isn’t a John Bachelor novella, but instead focuses on a conversation between Jackson Lamb and Molly Doran that fleshes out the former’s backstory a bit and includes a neat twist at the end. It’s very short, even by the usual standards, but it’s a great addition to the canon.

This was a nice short story to give some background about Lamb’s character. But it did feel a little out of place after reading book 1 since the only character in this story we know anything about is Lamb.

Not a big short story fan, but this one being tied to longer books was good. It appears though it's a little out of place at the end of the 1st book in the series and should instead have been read later.

I enjoy reading these head-to-heads between Jackson and Molly where they, with a mixture of contention and understanding, explore the past, which Herron reveals to us like an onion being peeled

This is a brief and entertaining story about spies in Berlin during the Cold War. It gives insight into the past of Jackson Lamb and is a great interlude in between the main Slough House books.

Enjoyed!

SPOILER:



























We are meant to think that Dominic Cross is Jackson. It isn’t. Molly is the woman in the photo.
