Seven Vampires: A Judge Dee Mystery by Lavie Tidhar

Seven Vampires: A Judge Dee Mystery1 by Lavie Tidhar (Tor.com, January-February 2022) is the fourth story in the writer’s ‘Judge Dee’ series, and opens with the vampire judge and his familiar Jonathan (the perpetually hungry narrator of the story) walking away from a Paris that is not only on fire but also experiencing a vampire pogrom. Further down the road they meet six other vampires and, after some tense introductions and exchanges (Judge Dee has to forbid the others from feeding on Jonathan), they later discover the body of a seventh member nearby, sans head.
As the group journey to Calais to get a boat to England we learn more about the various members (including the fact that Dee appears to be an enforcer of the Unalienable Obligations of Vampires) while, one by one, three of them are murdered.
By the time they get to Calais there are only four vampires left, and Dee eventually calls them together to solve the mystery of who the killer is (we then find out (spoiler) that Dee has previously tasked Jonathan to search the vampires during daytime for the evidence he requires to confirm his theories).
Dee explains to the group (“You might be wondering why I have assembled you all here”) that there are two killers: Jack killed Nils and Gregor with a silver knife (discovered by Jonathan) for a treasure map of a Western continent called Vinland (ditto), and Melissandra killed Lady Aisha, who she disliked, in an unrelated act. Dee throws the two miscreants overboard.
When the three remaining travellers arrive at Calais the (still religiously pious) Brother Borja steals the map and disappears. Judge Dee tells Jonathan that Borja will regret this due to the treatment of vampires on that continent.
This is pleasant enough fluff but it is one of those stories where only the author can solve the mystery as there are insufficient clues provided to the reader—who are little more than passive passengers for the duration of the tale (probably not a good thing in a murder mystery story, even a semi-humorous one).

1. I’m not sure why Tor didn’t keep the “Judge Dee and . . . ” format of the previous three stories, i.e. Judge Dee and the Seven Vampires.
