To Die For by David Baldacci (The 6:20 Man #3)

Some secrets are too dangerous to keep . . .
TWO SUSPICIOUS DEATHS
When Dwayne and Alice Odom are killed, the police report states clearly that it was a drug overdose. So why is their daughter, who was there when they died, claiming that's not the truth?
ONE YOUNG SURVIVOR
Betsy Odom doesn't trust the police but when she finds herself in the FBI's custody after her parents' deaths, she knows she has to be careful. Her uncle wants to adopt her and as he is a very rich and powerful man, she wants to let him. His criminal connections, however, mean the authorities aren't so sure.
ONE MAN ON THE RUN
Enter Travis Devine. Trying to escape a skilled predator who wants him dead, Devine finds himself as Betsy's bodyguard. But when an informant is found murdered, Devine knows this job is perhaps even more dangerous than the one he's running from . . . and the true enemy may be on his side.
