Beethoven's Assassins

Beethoven's Assassins is a novel by Andrew Crumey, nominated by publisher Dedalus Books for the 2023 Booker Prize. It imagines Beethoven being commissioned by a masonic lodge to write an opera about the Order of Assassins, called "The Assassins, or Everything is Allowed". The opera's subtitle comes from "Nothing is true and everything is allowed", which was the Assassins' secret doctrine according to Beethoven's acquaintance Joseph von Hammer-Purgstall.

The novel has multiple storylines set in different time periods with real-life characters including Therese van Beethoven (wife of Nikolaus Johann van Beethoven), Anton Schindler, J.W.N. Sullivan and Katherine Mansfield. The storylines vary in tone from comic to serious.

The first storyline is narrated by Beethoven's sister-in-law Therese and is comic. The second is narrated by a modern-day professor writing an article about "Beethoven and Philosophy". His work is interrupted by the pandemic and he starts writing about the troubles of his elderly parents during lockdown. After the pandemic he goes to a writing retreat in a Scottish country house where he resumes the Beethoven article.

There are other storylines set in the same house at different times. In 1823 the house is owned by a retired colonel connected to the masonic lodge who commissioned the opera. In 1923 the house is a psychiatric hospital visited by J.W.N. Sullivan, who in real life was an expert on Beethoven and physics. Sullivan investigates a woman able to recall past lives, and learns about the opera.

In Beethoven: His Spiritual Development, Sullivan argued that art is a kind of knowledge, different from scientific knowledge and complementary to it. Beethoven's Assassins develops this theme. The plot involves meserism, clairvoyance and psychic healing, mentioning Beethoven's connections with practitioners such as Johann Malfatti and Ludwig Schnorr.
