Yet another project to go unfinished

I'd like to write a science fiction story set in Zurich in 1916. Two time-travelling agents: one from the intertemporal avant-garde, the other from Control. The Control agent plans to kill Dada dead in the water by using mind control rays to ensure the audience for early performances at the Cabaret Voltaire find them boring. While he's at it, he'll do Lenin in as well by kaiboshing his deal with the Germans.
