Good Boy Protocol by Skye Arden

At Graybar Institute, ex‑detective Adrian Holt interviews Mara Kessler, a killer who only speaks in ring taps. He came for his brother’s “suicide,” but finds records rewritten—and a consent form signed by his dead father. When Graybar orders a “wellness eval,” Adrian learns how fast an investigator becomes a patient… a trained GOOD BOY.
