Anthony de Portnay Smythe is a mysterious figure. Gentleman by day, he steals secrets for the government by night. A Stolen Kiss! When Constance finds a man in her bedroom late at night, her first instinct is to call for help. But something stops her. The thief apologises and gracefully takes his leave...and a kiss for good measure. And Constance knows that won't be the last she sees of this intriguing rogue...
