Who Murdered Erica I? is an intriguing new mystery thriller series.

The story follows Astrid, a no-nonsense, cold-hearted detective shaped by a tragic past. When she learns that someone has murdered Erica Ivy, Astrid finds herself pulled off balance — unable to focus solely on seeking justice, because she and Erica once shared a dark and complicated history. Along the way, Astrid turns to her former criminal justice professor, Thomas, asking him to help untangle the case. Like Rafael, Thomas serves as a steadying presence, helping Astrid keep a clear head as she pursues leads and confronts painful memories. The main difference, however, is that Astrid and Thomas do not share a deep emotional bond the way Rafael and Hannah do; still, Thomas genuinely worries about Astrid’s safety and well-being. Their intertwined pasts and the unresolved threads between them are gradually revealed as they work together to solve the murder.

Erica I is a cold-hearted, manipulative woman who will eliminate anyone who stands in her way. Her callous treatment of others—unyielding, self-serving, and often cruel—has left her despised by everyone who has to be near her.
