“I’ve got a special .45 with an extra clip of cartridges. That ought to be enough for a trip like this.”

“Let’s hope so,” said the intelligence officer.

When they reached Antacostia, a cabin plane, a navy ship, was out on the ramp waiting for them. It was an amphibian and while they were paying the driver of their cab, the pilot started the motor with a roar that shook the ground.

An officer ran toward them.

“Which one of you is Bob Houston?” he asked.

Bob stepped forward.

“You’re wanted on the phone at once,” he said.

“Step on it, Bob. We’re ready to go,” warned Lieutenant Gibbons.

Bob ran toward the administration building and a clerk there handed him a telephone.

Bob recognized instantly the voice of the chief of the bureau of investigation. Waldo Edgar, usually so calm, was deeply moved.
