How Does The Best Crime Writer Build Tension In A Mystery Novel?

I'm a half-baked forensic examiner whose only redeeming quality is the ability to understand animals. The crime scene is inside a lavish villa. The lady of the house lies dead on the floor with a blunt-force injury to the back of her head so deep that her bone is visible. The safe has been pried open, and a million dollars in cash has vanished without a trace. Clear shoe prints mark the backyard wall, evidence that someone has climbed over it. "This one's clear as day. This is a textbook robbery-homicide. The suspect is likely a young male, around six feet tall, has a prior theft record, and knows how to cover his tracks. Check the surveillance footage in the area and look into places where he might've moved the stolen cash." The director of the forensic science center, Egbert Woodward, has been in the profession for three decades and is a widely respected authority. The officers at the scene nod in unison and begin taking notes. I'm the only one who stares at the 30 flies circling the ceiling for a full 3 minutes before taking a step forward and piping up, "Dr. Woodward, this isn't a robbery-homicide. It's a crime of passion. The murderer is the victim's husband!"

I quit and dipped. City threw a parade. Only Jenna Blake—my oh-so-gifted junior who claimed she could "see through killers' eyes"—lost it. At her celebration banquet, she went full drama queen: "I owe everything to Kate Mercer. Please, bring her back!" I laughed. Cold. Not happening. Last time around, I was the hotshot detective. But every clue I found? She dropped it first like she read my mind. People started saying I was washed. So I went all in—three months, no sleep, cracked a massive trafficking ring. Led the raid myself. She beat me there. Again. Place was cleaned out. Boom. She's the city's golden girl. I'm the clown with no game. Pressure got ugly. My head snapped. I died chasing the last scumbag. Then—bam. I woke up. Same day. Raid morning. Round two.
