Broken Lullaby.

Rich Hungarian-born orphan Katya Davidov commissions Jordan Kirkland to research her past starting from a photograph, showing her as a child next to an elusive Fabergé music box. Luckily experienced Yankee-Hungarian treasure hunter and womanizer Nick Rostov gently forces his help upon her, although Jordan stubbornly risks dealing with his dodgy competitor Gudrun Kuper and her ruthless employer, count Borodin.
