Hell's Corner by David Baldacci

An attack on the heart of power.. .
In sight of the White House . . .
At a place known as . . .
HELL'S CORNER

John Carr, aka Oliver Stone -- once the most skilled assassin his country ever had -- stands in Lafayette Park in front of the White House. Inside, the British prime minister is being honored at a state dinner. Then, just as the prime minister's motorcade leaves, a bomb explodes in the park, and in the chaotic aftermath Stone is given an urgent assignment: find those responsible.

British MI-6 agent Mary Chapman becomes his partner in the search for the unknown attackers. But their opponents are elusive, skilled, and increasingly lethal. Worst of all, the park bombing may have been only the opening salvo in their plan. With nowhere else to turn, Stone enlists the help of the only people he knows he can artist: the Camel Club.
