The Painted Face — Jean Stubbs

It seemed impossible at first. To track down a mystery so old. But fashionable artist Nicholas Carradine had become obsessed with the death or disappearance of his young half-sister, Odette, twenty years before.

And so he approached the famed Inspector Lintott, who agreed to take the case. Their search brought them to Paris where the good Inspector turned up some shockers for Carradine. For he had uncovered a trail of adultery and incest...and the incredible secret which could free - or destroy - Nicholas.
