In her book "Forensics," Val McDermid reflects on the dark realities faced by those in the field of forensic investigation. Despite being exposed to humanity's worst actions, she expresses a continual sense of shock at certain events. Unlike many professionals who can share their work experiences with family, forensic experts often deal with sensitive and disturbing content that they prefer to keep private.

This necessity for secrecy underscores the emotional burden carried by individuals in forensics. McDermid's insights highlight the unique challenges they face, balancing their professional responsibilities with a desire to shield loved ones from the grim details of their work. Through her writing, she opens a window into the complexities of dealing with crime and the profound impact it has on those who investigate it.
