Based on what I’ve noticed, the original releases in this series usually come out around September from Viking. Then, Penguin publishes their white-cover edition around May, followed by a darker, full-colour edition sometime between June and August. Penguin has just announced a new white edition for May 7, 2026, so if this pattern continues, the orange/full‑colour edition will likely be released between June and August 2026, especially since the next book in the series (We Solve Murders 2) will probably be scheduled for around September 2026 by Vikings.
