A Birthday's Dark Omen (Paperback) (ISBN-13: 9798288247132)

A class reunion at the venerable St. Severin school becomes a journey into a dark past for private investigator Alexander Freiherr von Tannenberg. The unsolved disappearance of a classmate twenty years ago casts a long shadow over the festivities.
When the reunion takes a bloody turn and a former classmate is murdered, Alexander is forced to launch his own investigation. Behind the ancient walls of St. Severin, he uncovers a deep web of old secrets, hidden guilt, and deadly intrigues. With each new victim, it becomes clearer that a ruthless murderer is on the loose, determined to settle an old score.
Alexander must delve deep into the abyss of the past to bring the truth to light-before it's too late, and the shadows of St. Severin claim even more lives.
