The Kaiser Affair

When a master thief escapes from prison, detective Bettina Rothschild must put him back behind bars before he destroys the Ministry of Justice. Her investigation leads from decaying cemeteries where ravens conspire to warehouses where wondrous machines are built in secret, and even to the fabled Drifting Isle above the city of Eisenstadt where an ancient tomb hides a deadly secret.

While Bettina picks locks and interrogates suspects with her many ingenious inventions, her dashing husband defends her from the most brutal and bizarre assassins in Eisenstadt. But can they find the thief before he brings the Iron City to its knees?
