Lineage most lethal

It's the week before New Year's Eve and genealogist Lucy Lancaster is mixing work and play quite nicely at the boutique Sutton Hotel in Austin, Texas. After two months of research she's finalising her presentation for hotel heiress Pippa Sutton, her latest client. Lucy has just arrived back at the hotel after a day of research when a strange man comes staggering toward her. She barely has time to notice his weak, sweaty appearance and broken tooth before he presses a classic Montblanc pen into her hand, whispers, 'keep them safe', and collapses at her feet, dead. Lucy only knows one person who might be able to explain the signifcance of the pen: her grandpa, who is a collector. But Grandpa has an odd reaction to the sight of the pen, and Lucy can't help but feel that it might have something to do with his experiences during World War II.
