Convention Killings Books in Order

Convention Killings begins with It Was Only On Stun!, Declan Finn's comic thriller set in the world of science-fiction conventions. The setting is full of costumes, fan arguments, celebrity guests, security worries, and people who are much more interesting than they first appear.

Sean A. P. Ryan is hired to provide security for a convention that is supposed to last three days. He expects the usual problems. Crowds can be difficult, guests can make demands, and conventions have their own special form of chaos. What he does not expect is a serious threat from someone who believes fantasy has become real.

Then the job becomes a hunt for an assassin.

The story uses the convention setting with affection as well as satire. Finn knows the rhythms of fandom, from the odd rules and rivalries to the way a seemingly harmless gathering can turn overwhelming once thousands of people arrive. Sean has to navigate that environment while trying to identify a killer before a threatened celebrity dies.

The book is a standalone-style thriller, but Sean A. P. Ryan becomes an important figure elsewhere in Finn's fiction. He later appears in the Pius books, where his abilities are used in much larger Vatican and international conspiracies. That gives readers a useful reason to begin here if they want to see one version of the character before the stakes become global.

The main appeal is the contrast between a playful setting and a genuine criminal threat. A convention can be funny, exhausting, and strangely intimate, but it also gives an attacker crowds, confusion, costumes, and many ways to disappear. Sean's job is to keep the place safe when normal security plans no longer apply.

Start with It Was Only On Stun!. It introduces the setting, the humor, and Sean's practical way of dealing with danger. Readers who enjoy him can then continue to A Pius Man, where he joins a larger ensemble of Vatican defenders, spies, and investigators.
