In this 15th (and final) novel in the Crispin Guest medieval noir series, Crispin and his apprentice Jack Tucker are hired to help the prioress of a convent discover who is behind a series of grisly murders of her nuns. They each appear to be related to the Seven Deadly Sins, begging the question of what the victims really had to hide. At the same time, Henry Bolingbroke, the exiled son of John of Gaunt, has returned to England with an army at his back. Crispin once again finds himself in a position where he has to decide whether to support the crowned king or to commit treason again, possibly paying for it with his life this time. 

For the past 15ish years, readers have followed along on adventures with Crispin Guest, former knight and lord of the realm, disenfranchised for treason when he threw in his lot with the supporters of John of Gaunt over King Richard II. He’s gone from being angry and bitter to content and even happy and loving his role as the indulgent head of a very rowdy house full of Jack’s children. He has learned that he is quite able to make a decent life for himself through his tracking skills, and has earned the appreciation of many Londoners by helping them. Certainly, he has done more good for the citizens than the sheriffs ever did, which makes him smug. So it has been fun to watch his progression over the years. 

Same with Jack. He went from being a 10 year old mongrel street urchin who seemed to be on a glide path to the gallows for thievery to a competent apprentice tracker, loving husband, and fun loving father. His character arc was almost as big as Crispin’s and it has been a joy to see how he’s grown over the years. 

Yes, these characters feel real to me. 

The mystery in this novel was a fun and twisty one, full of murder and theft and nuns! With! Secrets! It would have been a great read on its own, but I was so focused on all the stuff with Henry Bolingbroke and Richard II that the mystery sort of fell to the wayside with me on this one. Not because it wasn’t good or anything. I just wanted to know how it would all end! After the mystery was solved, I found myself covering up any part of the page I hadn’t read yet so that I wouldn’t accidentally read too far ahead and spoil myself. I think that is a mark of a terrific story. 

I could tell you how it ended. I could tell you what I thought about it. But then maybe you wouldn’t go out and read these books for yourself, and that would truly be a loss for you. I realllllly think you should read them all. You won’t be sorry you did and then, when you get to this book, you will be on tenterhooks to see what new awful thing Westerson might do to poor Crispin! And then you can mourn the last book in the series. And then you can go out and be excited to read the other books Westerson already has, and look forward to the new Tudor series she’s got in the works!
