Breach

Somebody is dead. Everybody had a reason. Breach is a collection of 150 murder-mystery logic puzzles in the classic deduction-grid style. Every case gives you a victim, three to five suspects, the weapons they carried and the places they were. Read the clues, mark the grid — ✕ to rule out, ● to confirm — and name WHO did it, WHAT they used and WHERE. THREE VOLUMES, THREE WORLDS • Breach — startups, server rooms and boardrooms. A CEO who never blinks during layoffs, an intern with root access nobody remembers granting. • Breach, Volume 2 — a Gulf family business empire: towers, majlis, desert camps and trading floors. Twelve suspects with everything to inherit. • Breach, Volume 3 — inside the cybersecurity industry: the SOC at 3 a.m., the incident war room, the hacker-con expo hall, the room with no phones.
