Shrouded in Thought - N. S. Wikarski - Bog

To solve baffling crimes in turn-of-the-century Chicago, you only need to know a single fact. Bygone sins in the White City cast the longest shadows.
GILDED AGE CHICAGO MYSTERIES
Gilded Age Chicago is the fastest growing metropolis in America, rivaling New York as the City of the Century. This melting pot of thieves and corrupt politicians, robber barons and immigrants, is rife with scandal and social injustice. An eccentric heiress and a star reporter find themselves repeatedly drawn into the hidden world of intrigue and murder that lurks within the shadows of the White City.
Volume 2 - Shrouded in Thought
When a factory girl crashes through a guardrail and accidentally drowns in the Chicago River, rookie journalist Freddie Simpson is convinced there's a sinister explanation for the incident. Nobody believes him, of course, so he decides to launch a solo investigation. The plot thickens once Freddie's prime suspect is also implicated in the poisoning of his friend Evangeline's neighbor. For the two amateur sleuths, a random drowning becomes intertwined with labor riots, a national railroad strike, a medium who speaks to the dead, a blackmailer, and a murderer intent on covering his tracks by any means necessary. In SHROUDED IN THOUGHT, a killer learns he can outrun everything except the ghosts of his own past.
