The First Chase. Lowan, #15

Meet Lowan, a telepathic alien working as a private detective in the 1930s!Lowan and Marx begin their hunt for the insurance fraud syndicate members. Their chase for answers entangles them in a brutal underworld beyond the city limits, where greyhound racing is the façade for a far more sinister crime. Shattered lives, fractured loyalties, and a trail of blood lead them to a man who faked his own death, but couldn't change his old habits.
A race-fixing scheme soon becomes the least of their worries, and more old enemies lurk in the darkness. Every clue plunges them deeper into an abyss of murder and desperate betrayals. The stakes are higher than ever, and one misstep could bury them. S. E. Grosskopf's writing is strongly influenced by the old pulp fiction magazines and Golden Age radio dramas of the 1930s-1950s. If you like fast-paced action and mystery with a dash of urban fantasy and quirkiness, then you'll love these books.
This is the fifteenth book in the series. The books follow chronologically. Reading them in order is recommended.
