It’s no secret to regular visitors to Linda’s Book Bag that I am a huge fan of M.W. Craven’s Washington Poe books. Consequently, when the latest book in the series, The Killer’s Mark, arrived in surprise book mail I was genuinely thrilled and there may have been* shouting in glee. I’m not quite sure who sent The Killer’s Mark, but thank you so very much! 

(*there was)

It’s my pleasure to share my review of The Killer’s Mark today and you’ll find my reviews of the other books in the series here. 

The Killer’s Mark is published by Constable on 13th August 2026 and is available for pre-order here. 

The Killer’s Mark

The next darkly-funny thrill-ride of a book in the bestselling Washington Poe series.

A MONSTER. A MOTHER. A MURDER?

When Vice Admiral Boyer, RN (retd) died without leaving a will, his estranged daughter inherited his- not inconsiderable – estate. Called home to sort through his belongings, she found an AegisBox – a tamper proof safe within a safe designed to self-destruct if anyone without the code attempts to open it. Faced with the choice of walking away or opening it, she opted for knowledge over silence and uncovered something so horrifying it launched the biggest investigation in the National Crime Agency’s history. Five years later, Washington Poe is unwittingly, and unwillingly, sucked into its gravity well…

Finally able to escape the authority they once railed against, Washington Poe and Tilly Bradshaw are enjoying their new jobs as private detectives or – as the sign on their door says – ‘Gumshoes for Hire’. When a teenage girl walks into their office, looking for the mother she has long believed to be dead, they agree to take the case. As Poe and Tilly investigate the girl’s claims, they find themselves drawn into a murky world of trafficking, pornography and prostitution. Will they be able to help the girl find her mother or will the dark forces at work, who will stop at nothing to protect themselves, get there first… 

My Review of The Killer’s Mark

Poe and Tilly have a new private investigator business.

I have a feeling The Killer’s Mark is going to be impossible to review because I absolutely do not want to give away spoilers. As soon as I had read the Prologue I knew this was going to be an extraordinary book. It is. It also confirms my suspicions that M. W. Craven is both terrifyingly skilled and possibly a little unhinged – in the best possible way – as no ordinary mind could construct this kind of plot. 

As ever with a Poe and Bradshaw book the pace is blistering, the short chapters refuse to let the reader step away from the narrative because, not only do they add momentum, they are so gripping with those trademark hooks at the end of each one that it’s impossible not to want to read on. The twists, the balance between keeping the reader informed and withholding just enough to have them completely ensnared in the narrative thrums through the pages. The trademark visceral nature of the story, the wit, humanity and technological science with which we are so familiar in a Washington Poe book are wonderfully resonant and yet feel fresh and vibrant within The Killer’s Mark. The main characters might be familiar but there is nothing repetitive or derivative in the storytelling. M. W. Craven is innovative and mesmerising with an assured sense of detail that is utterly convincing. 

Indeed, alongside a plot that is insanely intricate, brilliantly constructed and mind-blowingly entertaining, there is some fabulous character development here. If you’ve not read another of the Washington Poe books, there is enough of Poe’s past exploits referenced to give a rounded picture, but in The Killer’s Mark, he is given a slightly more tender trait so that his humanity is both presented more fully and tested to the limit. What I loved even more this time is that Tilly is becoming adept at her own deviousness too. The balance of familiarity and progression is so appealing. Add in the teenage, angst-ridden, foul mouthed Esmeree to the mix and the combination is both explosive and fascinating.

I’m aware I’ve said nothing at all about The Killer’s Mark – deliberately so as I really, really don’t want to spoil the read for others. However, one aspect I am willing to spoil is that the Epilogue, particularly the final sentence, made me cheer, but you’ll need to read the book to find out why!

Regardless of my inability to review it, I thought The Killer’s Mark was excellent. I absolutely adored being back with Poe and Tilly. I loved the attention to detail, the evident thorough research that has gone into making this another authentic and pulse elevating narrative, and the masterful storytelling which all add up to another roller-coaster ride. Don’t miss this one because it’s brilliant and if you haven’t read the other seven books in the series you are really missing out!
