If you only grabbed the solicit text, here is the durable version: X-Men: The Hellfire Murder (2026) #1 is Marvel's latest Hellfire Gala jam, on sale since July 22, 2026, with Wolverine and Jubilee stuck inside a locked-room murder mystery.
Spoiler-safe: what Marvel already sold
Marvel's issue page pitches the night in one line:
HOMICIDE AT THE HELLFIRE GALA! When an iconic mutant power player is murdered at an exclusive masquerade hosted by SEBASTIAN SHAW, it falls to WOLVERINE and JUBILEE to solve a locked-room mystery that has dire consequences for all mutantkind. Everyone is a suspect. And the party isn't over yet...
Luciano Vecchio's cover sells the chalk-outline energy. The creative bench is a rotating jam (Saladin Ahmed, Eve L. Ewing, Gail Simone, Jed MacKay, Erica Schultz among the writers).
Inside the party pages, Emma Frost and Namor share charged scenes. That pairing has history from the Utopia era, and this issue fans the chemistry again. Treat it as a character beat, not a published ongoing coupling announcement. Marvel has not solicited an Emma/Namor romance series off this one-shot.
Why Shaw's death matters in 2026 continuity
Post-Krakoa, mutant death is sticky again. Taking a classic Hellfire Club power broker off the board changes money, politics, and who inherits the Club's toys. That status-quo shift is the utility of the issue even if you skip ship discourse.
Spoiler wall: who killed Shaw
Stop here if you want the detective structure intact.
Wolverine's investigation surfaces a new Brotherhood configuration claiming credit with nerve gas, while the actual killing blow lands telepathically from Emma Frost before that gas story can finish the job. Logan clocks it and keeps the secret. Publicly, other factions can still believe their own versions of the night.
