Mathematician Olga Barkovskaya goes to a class reunion. But no one has any reason to celebrate. Their mutual friend Katya was recently killed by a mysterious robber. And this tragedy is far from the only one. Two more people died in accidents. The chain of strange deaths stretches back to the suicide of the reclusive Alina, who left behind an unusual note—a mnemonic poem composed for Euler’s chess puzzle.
When another death occurs among the former classmates, Olga notices a frightening pattern. The mysterious killer seems to be playing a game of chess, “moving” like a knight.
Will the mathematician-detective be able to solve the combination and identify the killer?
