What Happened to the Boy‪?‬

An intense fire destroys the palatial home of a prominent attorney and his wife. After their bodies are removed from the burning house, Sam Nagy is pronounced dead immediately; his wife, Alyssa, succumbs on the way to the hospital. The causes of death are due to bullet wounds—not the fire.
But what happened to their boy?
Thin Lizzy, a dowdy homeless person, who secretly resides nightly at the public library, knows about the boy, but she’s not telling.
