IN THIS THREE-BOOK BOX SET:

BOOK 7: THE CONDEMNED WOMAN
Lucienne Vallauris, spurned former lover of Count Alain d'Aubenas, stands convicted of strangling the Count's infant daughter in her cradle. The sentence is death...by guillotine. With witnesses placing her at the scene of the crime, no alibi, and incriminating evidence found in her home, the evidence against her is overwhelming, but Chantecoq is convinced she is innocent.

The clock is ticking for France's greatest bloodhound as he seeks to clear Lucienne's name and find young Marie-Anne's true killer.

BOOK 8: THE LADYKILLER
A maniac is striking down women in the street in broad daylight! For weeks, women have been dropping dead to the ground in public, the cause of their deaths as mysterious as their silent assassin. Chantecoq, however, finds the link connecting all the Ladykiller's victims, and realises he faces a deranged, unstoppable serial killer.

With his usual skill and resourcefulness, Chantecoq plays a cat-and-mouse game with the Ladykiller—but this time, could Chantecoq have finally met his match? Could this be his final adventure?

But the scientists are disappearing! Picked off by an international team of hired killers, led by a mysterious female assassin: the beautiful but deadly Devil's Daughter.

Older, wilier, and aided by his irrepressible secretary Meteor, Chantecoq's mission will take him far from Paris.

On the shores of Lake Michigan, France's greatest detective battles to decide the fate of the entire world.
