Sherlock Holmes and the Remaining Improbable

The aged and still cocaine-addicted Sherlock Holmes submits entry forms at a nearly defunct psychiatric clinic, naming a peculiar goal: "No more solutions, but true resolution," and finds that his worst enemy has left him the key to his wish, if he can give everything in return. Can his friend Watson stop the clock that has been ticking toward Holmes' demise, or will he be forced to sit powerless and watch as Holmes walks straight into danger?
