Sherlock Holmes has always trusted his mind to deliver certainty. Deduction restores order. Logic conquers chaos. Being right is the highest form of virtue. Until evidence agrees with him in ways that make him wish for error.
The pattern is clear: something is feeding on London, patiently and legally, with a time horizon no human criminal could possess. Holmes sees it long before he can prove it. And for the first time, his genius becomes a burden rather than a gift-a premature knowledge that forces him to watch harm continue while he waits for the evidence that will make others believe.
Dr. Watson watches his friend change. Not broken, not defeated, but carrying the burden of justice. Collect everything. Destroy Everything. The isolation of being right when rightness offers no consolation.
This is a story about what happens when the tools that have always saved you prove insufficient, when the only form of genius that works is persistence. How can Holmes outlast a creature that won't die?
