What are the motifs in A Simple Plan: A Novel by Scott B. Smith?

Suspicion is an important motif. From the very beginning, Hank, Lou and Jacob are caught in a triangle of suspicion that quickly expands to include everyone else who might have a connection to figuring out the truth about the money. This lack of trust is seen at the moment Lou questions the reason Hank should be the person to hold the money until the time for the division and moments later when Lou demands that they count the money before allowing Hank to take it home.
