A twin-swapping scheme propels this exceptional suspense novel from German bestseller Hammesfahr (The Sinner
). After meeting Susanne Lasko, a desperate, unemployed divorcée, by chance, Nadia Trenkler, a stylish Berlin investment counselor, hires Susanne, whom she closely resembles, to spend the weekend with her husband, with whom she barely interacts and who will be busy with his own work, so she can conduct an out-of-town affair. Of course, a lot more is going on than Susanne realizes. For one thing, Marcus Zurkeulen, a shady investor Nadia has been tricking, wants the money she stole from him. When the devious Nadia disappears, Susanne continues the deception with scary results. Hammesfahr does a superb job portraying Susanne's fearful descent into another woman's life. Full of clever and disturbing twists, this dark delight will please Patricia Highsmith fans. (May)
