J.L. Calder’s DoubleHelix Brings Gritty Political Noir to Washington D.C.
When a bestselling crime novelist uncovers a classified file in the National Archives, he’s pulled into a deadly CIA and MI6 conspiracy that threatens the President—and his own life.
Dwyer Street Press is excited to release DoubleHelix, the first book in The Helix Project series by new author J.L. Calder.
DoubleHelix is a fast-paced spy and political thriller set in today’s Washington, D.C. Bestselling crime writer Mike Green, famous for his hard-boiled Gestapo Joe novels, sneaks into the National Archives looking for story ideas. Instead, he finds a secret file that pulls him into a real-life conspiracy involving the CIA, MI6, a missing writer, and a possible threat to the President.
The story mixes classic detective noir with modern espionage, betrayal, and high-stakes danger. Readers follow Mike as his made-up world turns into a deadly fight for the truth.
“DoubleHelix is a gripping debut that fans of spy thrillers and political conspiracy books will love,” said Dwyer Street Press editor Sarah Lin.
DoubleHelix is available in print and digital formats.
