Absolute Power by David Baldacci

In a heavily guarded mansion in a posh Virginia suburb, a man and a woman start to make love, trapping Luther Whitney, a career break-in artist, behind a secret wall. Then the passion turns deadly, and Luther is running into the night. Because what he has just seen is a brutal murder involving Alan Richmond, the president of the United States, the man with . . . Absolute Power.

A riveting debut novel of murder, honor, loyalty, and betrayal that reaches all the way to the Oval Office. A vicious murder involving the president and his mistress results in a coverup orchestrated by the zealously loyal chief of security and the Secret Service. But, unbeknownst to the president and his lackeys, one unlikely witness saw everything. Will Americans learn the truth?
