Upon reaching the lodge they found the three stay-at-homes looking the pictures of peace and contentment, and immediately set about trying to spoil things for them, as Amy languidly complained.

Having packed all their belongings the day before, it was necessary to reverse the process now that the safety of the lodge was assured. This occupied much of the afternoon, and as the shadows became longer they were oppressed by a strange uneasiness. In every rustle of a leaf, in every cracking of a twig outside the lodge, it seemed they could detect the furtive approach of some of the motley crowd who made their home in the swamp. The air seemed to be murmurous with whispers, the sighing of the wind through the trees took on a weird and wailing sound as though uneasy spirits roamed the woods.

“If radio doesn’t get in some fine work pretty soon,” grumbled Amy, “I can see where our last few days here are going to be spoiled. I can see a ghost in every shadow.”

As though to bear out her assertion there came from the direction of the swamp a faint wailing, growing steadily louder in volume—rising to a shriek and dying off into a frantic sobbing sound.

Again and again it came, and the girls crowded into the living room as though for mutual protection and stared at each other in growing perturbation.

At that moment Darry and Fol burst into the room with Burd limping manfully after them. Behind them came three men, who, despite the fact that they wore no uniform, bore the unmistakable stamp of police officers.

“We are just in time for the entertainment, I see,” said the tallest of the three, with a grimness of tone that fell reassuringly upon the electric tension in the room. “These hut dwellers have decided to give a special demonstration for our benefit, evidently.”

The three men, led by Aunt Emma, marched into the room recently occupied by Phrosy, and the boys lingered behind for a word with the surprised and excited girls.

“We bumped into these officers just as we were coming in,” said Burd. “They received the radio message and have men planted down by the swamp ready to close in on the hut when they give the signal. Come along, if you want to be in on the big show.”

“But, Burd, your foot! How can you go?” protested Amy, and Burd looked down at the injured member contemptuously.
