John Dickson Carr 
Ghosts’ High Noon [EPUB ebook] 

Jim Blake, journalist and successful spy novelist, is sent to New Orleans to do a story on James Claiborne Blake, a congressional hopeful in the 1912 election. But even from New York he senses following eyes. James Blake, it seems, is threatened by sexual indiscretions. And as the plot thickens, both Blakes become involved in politics and intrigue – and then impossible murder – among the atmospheric byways of New Orleans. 'A wonderful period piece that includes some fascinating real-life characters’ Saturday Review
