“I would so much rather you shot him than I,” said Leon earnestly. “The police are very suspicious of my shootings, and they never wholly believe that they are done in self-defence.”

With a rope he tied the man, and tied him uncomfortably, wrists to ankles. That done, he made a few inquiries and went swiftly out to the barn, returning in a few minutes with the unhappy guard.

“It can’t be helped,” said Leon, cutting short the man’s apologies. “The question is, where are the rest of the brethren?”

Something zipped past him: it had the intensified hum of an angry wasp, and a second later he heard a muffled “Plop!” In a second he was lying flat on the ground, his Browning covering the hedge that hid Heavytree Lane.

“Run to the house,” he called urgently. “They won’t bother about you.” And the guard, nothing loth, sprinted for the cover of walls.

Presently Leon located the enemy, and at a little distance off he saw the flat top of the covered trolley. A man walked slowly and invitingly across the gap in the hedge, but Gonsalez held his fire, and presently the manœuvre was repeated. Obviously they were trying to concentrate his mind upon the gap whilst they were moving elsewhere. His eyes swept the meadow boundary—running parallel, he guessed, was a brook or ditch which would make excellent cover.

Again the man passed leisurely across the gap. Leon steadied his elbow, and glanced along the sight. As he did so, the man reappeared.

Crack!

Gonsalez aimed a foot behind him. The man saw the flash and jumped back, as he had expected. In another second he was writhing on the ground with a bullet through his leg.

Leon showed his teeth in a smile and switched his body round to face the new point of attack. It came from the spot that he had expected: a little rise of ground that commanded his position.
