Dying to Meet You — B. Robert Anderson

Dying to Meet You revolves around a signature killing, in fact around several killings. Why the signature? Who is using someone else's identity? Stephen Eliot lived by the cliché. He also died that way.
Again, Lieutenant RC Frane and his partner, Sergeant Greta Rogers track much of the mystery through the food industry, but in a new direction. Thousands of canned tomato products destined to top pizzas in Philadelphia. Food broker, Stephen Eliot also has some interesting needs, before he is murdered.
Overlapping crimes complicate figuring out who did the deeds. Through gentle persistence, the two officers peel away events to solve what originally looked like serial murders.
