Books in the Joe Scintilla Mystery series

In the tradition of the old "Ace Doubles" two-in-one books (flip one over to read the second title)--here is the first Wildside Mystery Double, featuring two new novels of the 1930s private eye, Joe Scintilla: CONSPIRACY OF SILENCE, by S. T. Joshi. When the lovely Lizbeth Crawford walks into Scintilla's office, she tells him that her father, wealthy industrialist James Crawford, did not kill his brother Frank, even though he confessed and is now serving a prison sentence. Is Crawford shielding someone? Why are both his mother and wife happy to have him imprisoned? And why did Frank's fiancée commit suicide shortly after his death? TRAGEDY AT SARSFIELD MANOR, by S. T. Joshi. Members of the Sarsfield clan have gathered at the palatial family estate under terms of the will of John Sarsfield, who created a riddle they must solve to inherit the family fortune. Scintilla is summoned by his friend (and heir), Charles Jameson, who was found holding a dagger that had been plunged into the back of his aunt, another potential legatee. But the crime is only the final act of a tragedy reaching back centuries. Can Scintilla discover the truth before his friend is convicted?
