Every twenty meters or so Wilson would call out to Tuffy, who would bark some times but not others. After close to an hour of crawling, the barks finally began to sound like they were getting closer. After almost exactly an hour, Wilson could hear two things: Schmidt beginning to sweat up on the surface and the scrabbling sounds of a creature moving some distance ahead.

The tunnel suddenly widened and then disappeared into blackness. Wilson carefully approached what was now the lip of the tunnel, took the light out of his mouth and panned it around.

The cave was about ten meters long, four or five meters wide and roughly five meters deep. To the side of the tunnel lip was a pile of scree that formed a steep slope to the floor of the cave; directly in front of the lip, however, was a straight drop. Wilson’s light played across the scree and caught glimpses of dusty paw marks; Tuffy had avoided the drop.

Wilson directed the light to the floor cave, calling out to the dog as he did so. The dog didn’t bark, but Wilson heard the clitter of nails on the floor. Suddenly Tuffy was in the light cone, eyes reflecting green up at Wilson.

“There you are, you little pain in the ass,” Wilson said. The dog was dusty but otherwise seemed unharmed by his little adventure. He had something in his jaws; Wilson peered closely. It looked like a bone of some sort. Apparently, Tuffy wasn’t the first live animal to get sucked down into the fleur du roi after all; something else fell in and escaped down the tunnel behind the tear, just to die in this dead-end cave.

Tuffy got bored of looking into the light and turned to wander off. As he did, Wilson caught a glimpse of something sparkly attached to the dog; he trained his light on the animal as it moved and focused on the sparkly bit. Whatever it was was stuck to Tuffy in some way, encircling one of the dog’s shoulders and riding around to his undercarriage.

“What the hell is that?” Wilson said to himself. He was still following Tuffy with the light, which was why he finally saw the skeleton of the creature the dog had taken his chew toy from. The skeleton was roughly a meter and a half long and mostly intact; it was missing what looked like a rib—which was what Tuffy was now chewing on quite contentedly—and its head. Wilson flicked the light slightly and caught the white flash of something round. Ah, thought Wilson. There’s the head, then.

It took him a few seconds to realize that what he was looking at was the skeleton of an Icheloe adult.

It took another few seconds, and Tuffy wandering through the light cone, sparkling as he did so, before Wilson realized which Icheloe’s skeleton it was likely to be.
