I've made my way through the designated Slough House books by Mick Herron as of 8/24, and three of the novellas that are within the world, including The List, The (Marylebone) Drop, and The Catch, all of which I reviewed here. I also recently read The Secret Hours, which is part prequel, going back to when Jackson Lamb was in Berlin.
So what to do? I decided, thanks to a comment by Rosemary to read the other two novellas found in this volume, The Last Dead Letter and Standing by the Wall. The Last Dead Letter is basically a report Slough House archivist Molly Dornan gives of her findings to Jackson Lamb that reveals the meaning behind a photograph she found of Lamb and a woman in Berlin some years before. One idea here is to find out why Lamb--the hard-drinking, heavy-smoking, farting, darkly wisecracking cynical head of Slough House--is like this? What makes him tick? And in The Secret Hours and in this book you begin to get a few answers. Some insight. And again, it’s an expansion/backstory of the Slough House world. It’s really a short story, not a novella, that Molly tells of “Dominic Cross.” But in case you think you
can guess what this relationship is, think again. Writers such as Herron promise twists, and deliver.
The last novella, “Standing by the Wall” takes place at Slough House on Christmas Eve, beginning with Lamb telling Roddy Ho that he has to eliminate somebody asap. Christmas? Bah Humbug for Lamb, but Roddy Roddy Roddy! Ho Ho Ho! For the Rodster, of course, this might be an opportunity to shine! A chance for real action! But it turns out not to be about actual murder, but about altering the photograph Molly Foran had found. Get rid of this woman. What happens is part of the story, a Christmas story, after all, where the other slow horses try to ditch Roddy to get drinks in the bar at end of shift, Christmas Eve. Ho ho ho, indeed!
