“Memory of a Killer” airs as a weekly FOX drama that premiered with a two- night event and then settles into a regular weekly slot.

Quick Scoop: What day does Memory of a Killer come on?

  • FOX scheduled Memory of a Killer as a two-night premiere, with Episode 1 on Sunday, January 25, 2026 at 10 p.m. ET after the NFC Championship, and Episode 2 on Monday, January 26, 2026 at 9 p.m. ET in its regular time period.
  • After that event launch, it continues with weekly episodes, with listings showing Episode 3 on February 2, 2026, and subsequent episodes airing on the following Mondays (Feb 9, Feb 16, Feb 23, etc.), which confirms Monday as the ongoing broadcast day in the U.S.
  • A detailed production breakdown notes a 10‑episode first season running from late January through late March 2026, all aligned to Monday air dates after the initial Sunday premiere.
  • FOX and entertainment outlets describe the series as a new crime‑drama thriller led by Patrick Dempsey, marketed in the vein of high‑intensity shows like “24” and “House,” which is why it gets a prime midseason slot.

So in plain terms:

  • Debut: Sunday, Jan 25 (special event), plus Monday, Jan 26.
  • Regular schedule: Mondays on FOX in the U.S., with new episodes rolling out weekly through March 2026.
