My Gal Sunday by Mary Higgins Clark

HENRY PARKER BRITLAND IV IS WEALTHY, WORLDLY AND STILL YOUTHFUL AND ENJOYING AN EARLY RETIREMENT. HIS NEW WIFE, SUNDAY, AS CLEVER AS SHE IS LOVELY, HAS JUST BEEN ELECTED TO CONGRESS IN A STUNNING UPSET VICTORY THAT HAS MADE HER A MEDIA DARLING. HENRY AND SUNDAY MAKE A FORMIDABLE TEAM AND NEVER MORE SO THAN WHEN THEY SET OUT TO SOLVE BAFFLING CRIMES OCCURRING AMONG THEIR FRIENDS IN POLITICAL HIGH SOCIETY. FROM A LONG UNSOLVED CASE RECONSTRUCTED ABOARD THE PRESIDENTIAL YACHT TO A KIDNAPPING THAT BRINGS HENRY FRANTICALLY BACK TO THE WHITE HOUSE, THE FORMER PRESIDENT AND HIS BRIDE ENGAGE IN SOME OF THE MOST AUDACIOUS AND ORIGINAL SLEUTHING EVER IMAGINED.
