Early suspicions point toward her brother and past legal enemies

William, her brother, was with Merritt on the ferry when she vanished, so he became a prime suspect in Dept. Q’s reopened files. He had faced emotional challenges for years and was recovering from an accident that had changed his life.

Detectives learn that Merritt’s career as a prosecutor created tension with people she prosecuted. One notable figure was Graham Finch, a wealthy businessman she failed to convict in a high-profile murder case. These factors cast suspicion on William, Finch, and others.
