Solita and the Spies — Barbara Cartland

Solita Gresham's shock upon arriving at Calver Castle was twofold. Not only had her Guardian, the formidable Duke of Calverleigh, forgotten he even had a Ward, but the sensuous and reckless peer was enmeshed in the exotic wiles of a sinister Russian Princess -- his Country's enemy! It was by chance that Solita discovered the treacherous beauty's deadly purpose, but it was love that fired Solita with the courage to rescue the willful Duke in a breathless adventure of international espionage -- and reap the heart's sweet reward of a lifetime of rapture.
