But as Grigori and Benjamin are about to discover, they've both been briefed for the wrong mission.

Benjamin pauses in the shadow of an ornamental buttress at one corner of the chapel, and scans the darkness beyond. There are low shrubs, and a row of lichen-encrusted gravestones, some of them leaning towards a low dip in the ground where a willow tree holds court over a circle of beeches. He sniffs. There's something in the air tonight—something beyond the efflorescences of pollen spurting from the wildly rutting vegetation, something beyond the tang of mold spores drifting from the cut ends of the lawn over by the road. His eyes narrow. Something about the bushes is wrong.

His pager vibrates. He peers into the gloom, tensing and raising the heavy shotgun, and tries to move his right foot forward into a shooter's stance.

His boot is stuck . . .

Grigori crouches in the darkness behind a drunkenly leaning gravestone. His nostrils flare. The ground here smells bad, in a way that reminds him of a mass grave outside a nameless village near Rakhata in the mountains above Botlikh. Damp ground, rainy hills, and a season of death had soured the very earth, making the nauseous soil threaten to regurgitate its charges. After a week on duty there he'd had to indent for a new pair of boots: no matter how he scrubbed and polished he couldn't get the stench of death out of his old ones.

Grigori frowns, and raises his bow, sighting on the buttress to the right of the chapel, where he is sure the sentry will appear in a few seconds. His view is partially obstructed by the gravestone, so he tries to move his left foot sideways a few centimeters.

His boot refuses to shift.

Meanwhile, on the other side of the chapel wall, Benjamin slaps his pager into silence then tries to lift his right foot again, freeing it from the root or wire or whatever he's caught on. His left knee nearly buckles. Something has caught on his right ankle. Cursing silently, he glances down.

Grigori's nostrils widen as he smells rottenness, mold, and mildew. He shifts his stance slightly as the ground softens beneath his right foot. There's a faint vibration underfoot. Do they have earthquakes in England? It was once like this in the mountains near Botlikh—but the vibration is getting stronger. He glances aside, and sees the ground rippling.

Oddly, none of the bells are sounding—not in this chapel, nor in any of the others.

Benjamin sees something moving in the loose soil underfoot. Adrenal glands squirt, and his pulse spikes: he unslings his gun and turns it, slamming it butt-first on the white and crawling thing below, thinking snake—

A second hand, less fully skeletonized than the first, pushes through the soil and grabs the shotgun's dangling tactical sling.
