What’s in it?

Products & advertising1/5
Why this rating?

Mentions of real-world locations and consumer goods are used to establish setting, not for explicit promotion.

Death of a character4/5
Why this rating?

Murder and its investigation are central to the plot, with victims and serious consequences shaping the story.

Graphic injury3/5
Why this rating?

Some forensic and crime scene detail is provided, but it is not gratuitously graphic or overly prolonged.

Strong language2/5
Why this rating?

Realistic police-procedural dialogue includes some profanity and strong language, though it is not the book’s main focus.

LGBTQIA characters2/5
Why this rating?

Major detective Milo Sturgis is openly gay, and his identity is part of his personal and professional characterization without being the central theme.

Romance2/5
Why this rating?

Romantic relationships and personal histories appear in the detectives’ lives, but romance is secondary to the murder investigation.

Frightening scenes3/5
Why this rating?

A sustained murder investigation, threatening situations, and disturbing criminal behavior create notable suspense, but this is a realistic thriller rather than horror.

Why this rating?

There are some adult sexual references or themes connected to characters and motives, but no indication of explicit sexual scenes.

Alcohol or drugs2/5
Why this rating?

Adult characters may drink socially and use tobacco in realistic settings; substance use is present but not central or glamorized.
