Blood Oath — David Morrell

He wanted to make peace with the past...

Peter Houston just wanted to find the grave of the war-hero father he never knew--a yearning that would draw him thousands of miles from home to the military cemetary in France.

Instead, he stumbled into a shadowy underworld...

He enver dreamed his private pilgrimage would unearth a decades-long secret that would plunge him into a deadly labyrinth of intrigue and murder.

Now, he's fighting for survival...

As ruthless assassins hunt him through the cities of Europe, he'll struggle to stay alive. But when they murder the woman he loves, he'll turn from hunted to hunter.

And swearing a blood oath of vengeance...

Tracking down his ruthless tormentors, he'll discover a truth he could not imagine..and could possibly destroy him.
