He carried secrets. His final delivery cost him his life. Now, nearly forty years later, Sherlock Holmes is asked to follow a trail of hidden truths, corrupt power, and buried lies through the streets of New York. Can you uncover the truth before the case grows cold once more?

A snowstorm, a yellow taxi, a jazz bar glowing against the dark — and a delivery that never arrived. Work through Esme Whittaker’s plea, the journal, the witnesses, and the alibis, and open the briefcase that Vinny died carrying.
