Was Harper Ellis murdered or was it suicide?

Harper Ellis had everything to live for—a promising career as a beloved elementary school teacher, a tight-knit group of friends, and a dream wedding on the horizon with her fiancé, Daniel Kessler. Life in her beachfront condo in Panama City Beach, Florida, should have been the start of her happily ever after. But on the evening of January 26, 2021, Harper was found dead—brutally stabbed twenty times in her own home.

Daniel swears he left her alive just thirty minutes earlier. When he returned, the condo was locked from the inside, the security bar engaged. His frantic messages went unanswered, his texts turning from confusion to fury. For an hour, he called, he threatened, he begged. And when he finally forced his way inside, Harper was gone.

What happened in that locked condo? Investigator Lucas Burke is determined to find out. And this time he has to do so without his partner in crime, Alix Blade.

The authorities ruled it a suicide—despite a crime scene that told another story. A knife still embedded in her body. Deep, violent stab wounds, some to her spine and neck. Bruises in different stages of healing. A trail of forensic inconsistencies, overlooked or dismissed. A fiancé whose alibi unraveled under scrutiny. And a police department under pressure to close the case.

But the truth won’t stay buried.

As Harper’s sister hires Burke to fights for justice, shocking details emerge—secrets hidden beneath the surface of a perfect life. Was Harper a victim of intimate partner violence ignored until it was too late? Or did someone else have reason to want her silenced? And if this was murder, how did the killer escape a locked room?

In the vein of Gone Girl and The Girl on the Train, Day and Night is a gripping psychological thriller that will keep you questioning every twist until the final, chilling revelation.
