Within minutes of their deployment the skimmers resurfaced and gunned to top speed, streaking at better than eighty knots, moving like hot oil on Teflon. As they leaped from the surf, narrow wakes of foam kicking up in their slipstream, the divers rapidly abandoned the craft, extracted their rifles and nightscopes from their watertight cases, and began stealing inland on foot.

Several hundred yards downbeach, Vladimir Starinov’s cottage perched on its low, isolated bluff, its guards unaware of the approaching killers, its windows still throwing their fragile light into the darkness.

Lifting the teapot from the stove, Starinov moved to his table nook and poured boiling water into his cup.

Before sitting down, he took a dog biscuit from the box on his counter and called Ome through the kitchen archway, holding out the treat, hoping it might settle the animal. The dog glanced at him but didn’t budge. Moments earlier, he had padded out of the room and flattened onto his belly near the front entrance, whining and sniffing, his tail switching back and forth.

At first Starinov had thought the shrill whistling of the teapot was the cause of his pet’s skittishness, but now, despite repeated goading, Ome continued lying by the door, ignoring his master.

Starinov shrugged, dropped the spurned biscuit into a pocket of his robe, and blew on the tea to cool it off. Although the dog’s behavior was perhaps a little unusual, he didn’t think too much about it; Ome sometimes became agitated by the guards making their rounds, and this was probably the case tonight.

Well, fine, let the dog stay where he was, Starinov thought. The minister was feeling rested and relaxed after his walk on the beach, and wanted to savor that rare state of affairs.

The little nuisance was certain to be underfoot soon enough.

Outside the dacha, the guard in the Russian army uniform had thought he heard a sound at the foot of the bluff and had gone to investigate, aware it was most likely nothing—the wind rustling up sand or a twig, some sort of foraging rodent.

Now, glancing over toward his teammate at the far side of the cottage, he wondered if he ought to beckon him over, but then he saw the orange glow of a cigarette in his hand, and figured it wouldn’t hurt to leave him be.

He climbed down to the foot of the embankment, stopped, looking and listening. Moved a little farther out onto the beach and paused again. His brow furrowed. While he’d seen no sign of movement in the sand, he thought he heard a different noise now, a drone, like that of an approaching engine. No—many engines. Still a distance away, but getting nearer. It sounded like wasps to him. A whole nest of wasps. But what did it have to do with the whispery rustling he’d heard? And might it signal a threat to the minister?
