More than a century ago, a diagnosis of tuberculosis meant almost certain death for the patient.
Medical science desperately searched for a cure.
Then physician Robert Koch announced success: he could stop TB.
Another physician, Arthur Conan Doyle, took great interest.
And the creator of the fictional Sherlock Holmes ended up turning against Koch.
The story of the two men and the disease is told in Thomas Goetz's The Remedy: Robert Koch, Arthur Conan Doyle, and the Quest to Cure Tuberculosis.
