PERSPICIO

In an isolated psychiatric institution known for housing the country's most dangerous patients, Severus Snape works as a night nurse. Cold, methodical, and nearly impossible to intimidate, he is one of the few staff members capable of handling the residents of the fourth floor a special unit where four men, as brilliant as they are unstable, are confined.

Sirius Black, a charming and unpredictable man prone to sudden bursts of violence.

James Potter, an intelligent manipulator whose smile hides something deeply unsettling.

Remus Lupin, calm and observant, capable of reading people with terrifying accuracy.

Peter Pettigrew, quiet and nervous, always lurking in the others' shadows.

Before long, Severus notices that the four patients have developed an unhealthy fascination with him. They know his habits, anticipate his reactions, and always seem one step ahead of the medical staff.
