A book about poisons

A muscular man with a slicked-back hairstyle sits on a brown couch, holding a piece of paper in his left hand and gesturing with his right hand as he speaks. He shifts his gaze between the paper and the camera, his facial expressions changing as he talks, with his mouth moving and his eyebrows raising and furrowing. The scene is set indoors against a plain wall, with the man remaining seated throughout the loop.
