This Christmas, London awakens not only under the snow... but under threat. Every ten years, the city witnesses a red snowfall that heralds death and mystery. Now, Holmes and Watson must confront a phenomenon that defies logic, science, and ethics: an impossible mineral, messenger flakes containing secrets from the past, and a killer who seems to control the very weather.

From the snowfalls of 1840 to the most recent, on Christmas Eve of 1900, a dark pattern connects victims, warnings, and a legacy of experiments that put the lives and morality of those who uncover them at stake. Every flake tells a story, and this time, the message is directed squarely at Holmes... and Watson.

Amid guided blizzards, hidden laboratories, and long-held secrets, the detectives must decipher the truth before the next snowfall claims their best friend.
