Dark Keys of Uncomplacency

It's 1874, only a few years after the U.S. Civil War and Heinrich Schroder decides to leave his home country of Germany and settle in the modest city of Baltimore. An aspiring world-class composer, he quickly finds himself working under the lids of Steiff pianos ("Steiff" being the main manufacturer in the city), tuning the strings he so longed to master. Not long after his establishment in America, his clients and their families, some he considers friends, are murdered one-by-one.

Deemed a prime suspect early on, Heinrich must work to clear his name by assisting the police in apprehending the real killer--months after the unsolved murder of his own friend, Klaus Planck and his girlfriend, the beautiful Emma Jung. What Heinrich didn't know was that this serial killer encounter would entangle the life of Allison Scott, an unassuming girl who has just moved to New Castle with her family--over 130 years later.

In the summer of 2017, when days should be full of soccer and baseball and lounging the new house, Allison and her brother Julian are taken by surprise when they discover an old Steiff piano in the basement of the house across the street; a piano they believe to be haunted by the same serial killer that Heinrich Schroder was after. With her very own musical acumen, Allison works to solve the case of "Steiff-ling Slasher", picking up where Heinrich left off. Her life depends on it.
