“That’s the plague of it,” he grumbled. “If you could see them you could blast them from the sky even at night.”

Backing away, he studied the mass of masonry above him. More a fort than a castle, it had stood there for hundreds of years. Bombs had shattered it more than twenty years before.

From the very top of that tower had come a flash of light.

“The dog had found the Fugitive”

“Spy!” His mind registered like a recording machine. “Flashing signals!”
