323 Sapphires in Siam

Bored with London society and the 'Ladies of Quality' who throw themselves adoringly at his feet, the heartbreakingly handsome Osmonde, Marquis of Vale is almost relieved when the Siamese Ambassador brings terrible news from Bangkok. A waterlogged corpse wearing the signet ring of his friend, fellow adventurer and international spy, Calvin Brooks has been found. Suspecting foul play, the King of Siam summons him to Bangkok to investigate.
But first he must inform 18-year-old Ankana Brooks that her father is dead and that he is now her guardian. It does not go well.
"That is not true! Papa is not dead!"
The beautiful, headstrong young woman demands to go with the Marquis to Siam. He refuses – but as his yacht The Sea Horse nears Gibraltar, he discovers Ankana stowed away! Past the point of no return, he reluctantly allows her to stay aboard, disguised as a far younger girl so that no eyebrows will be raised.
On their perilous journey from the King's palace to Chiang Mai, their mutual irritation chafes more and more, until it dawns on Osmond how Ankana more than lives up to her name, which means 'beautiful woman' in Siamese. Ankana is driven to a jealous fury when he visits the Madame of a famous 'palace of pleasure', and an accidental kiss changes everything. Finally, in a Pattaya temple, Ankana finds her father alive, disguised as a Buddhist monk and fighting for his life with robbers stealing holy sapphires from The Buddha's gilded feet.
