Wolf drew away from the checkpoint. He kept well out of sight as he worked his way around the side of the big house, threading through the trees. Karswell Hall was a hell of a grand old country pile, a real billionaire pad, its scores of windows lit up like a starship with exterior floodlamps casting a glow over the immaculate lawn that sloped down from the rear towards a gleaming dark lake at whose centre was a small wooded island, all wreathed in shadow. The gathered guests, maybe fifty or sixty of them, were visible through the windows of the manor, standing in groups, talking, sipping drinks. The men-only gathering was obviously a formal event, judging by the sombre suits and ties of everyone present. Wolf noticed that there was not a single woman among them.

Crouched down low and invisible among the trees, Wolf used his compact but powerful telephoto lens to search for Abbott among the guests, but couldn’t make him out in the crowd. Maybe he’d get a shot at his target that night, or maybe not. He kept waiting, and watching.

He had no idea what he was soon to witness.

At the stroke of midnight, the ceremony began.

It was like watching a surreal dream unfold. First the lights went out and Karswell Hall fell into darkness, illuminated only by the pale glow of the full moon that hung over the lake. Minutes later, a procession of figures slowly began to emerge from the rear of the house and wind its way down the lawn towards the water’s edge. But, as Wolf realised, there was something bizarrely changed about the figures. All fifty or sixty guests were now wearing strange robes, long, dark, and hooded. Their faces were obscured by black masks. Wolf felt a tingle of apprehension as he saw they were animal masks – no, bird masks, with curved, sharp beaks that reminded him of the head of the old man’s cane.

The procession assembled at the lakeside. They stood shoulder to shoulder with their backs to the trees where Wolf was hiding, all looking out across the water towards the dark, wooded island at its centre as if full of anticipation for something about to happen there. He scanned the crowd, still searching for Abbott, but it was impossible to tell whether he was among them or not. The hooded men were unrecognisable, all except for the thin, stooped figure that walked with a noticeable limp and leaned heavily on a cane.

Wolf breathed, ‘What the f—??’ He knew that he had to capture this on video. If he didn’t film what was happening he’d have a hard time convincing himself afterwards that he hadn’t been dreaming. He quickly set the phone camera and hit the record button.
