The Valley of Fear

A murder drives the investigation, a character is apparently killed, and Douglas is later reported lost at sea and presumed dead.

Mention of a gunshot wound to the face, though described in the measured prose of the period.

Standard literary language of the period; no modern profanity.

A priest hole and religious setting detail appear, but faith and religious practice are not central themes.

Minimal; the plot centers on mystery and danger rather than romantic relationships.

Sustained suspense includes murder, threats, a hunted protagonist, a murderous gang, nighttime surveillance, and a presumed death. The tone is tense and ominous rather than horrific.

Social drinking and tobacco use typical of the era are briefly present.

Murder, attempted shootings, gang violence, threats, undercover pursuit, and criminal coercion are central to the plot.
