Man walking down a brick sidewalk in a business suit reading a paper and smoking a cigar with a woman wearing sunglasses walking behind him to his left.
The woman is a secret agent on mission to murder the man.
She could just be walking,  no reason to infer she is a secret agent on mission to murder the man.
A woman is walking behind a man doesn't necessarily mean that she is a secret agent on mission to murder the man.
Just because the woman wearing sunglasses is walking behind the man does not mean that she is a secret agent on a mission to murder the man.
