The door is open. How big is this place, anyway? The Ancient Order of Wheelwrights must have been rolling in cash. The sacrificial cortege begins to move again, and now the cultists around me begin to sing a curious dirge-like song. We're descending across broad steps—almost two meters wide, topped with dusty mattresses to either side—towards a central depression beneath a low, vaulted ceiling. The skullfuckers probably used this space for their orgies, more than a century ago; it's haunted by the ghostly stink of bodily fluids. We've been brought up to think of the Victorians as prudes, horrified by a glimpse of table leg, but that myth was constructed in the 1920s out of whole cloth, to give their rebellious children an excuse to point and say, "We invented sex!" The reality is stranger: the Victorians were licentious in the extreme behind closed doors, only denying everything in public in the pursuit of probity.

Now the cultists around me are breathing faster, raising their voices higher, trying to drown out the phantom sighs and moans of a thousand dead and withered seducers. I try and keep to my own chant, but it's hard to focus on suicide when all around you the ghosts of gluttony sleep so lightly.

There is a huge bed at the center of the well of mattresses: a four-poster, canopied in rich black brocade, ebony uprights supporting a drapery as ornately swagged as any Victorian hearse, with a huge chest sitting in front of its footboard. The bed alone is wide enough to accommodate half a dozen—not sleepers, I realize—although only two bodies lie there now, curled in fetal death, close to one side.

As the singers continue, two of Iris's minions walk up to the bed. They raise the quilt piled against the footboard, covering the mummified occupants; then they take hold of cords dangling from the base of each post and attach manacles to them.

"No," I say. "No!" Then I try to bite the hand that's reaching in front of my mouth with a gag.

"Mummy said not to hurt you unnecessarily," Jonquil explains. "So open wide, or—" Her other hand grabs my crotch and squeezes. I gasp in pain. Bitch. "Good boy!"

When they dump me on the counterpane a cloud of stinking dust billows out in all directions, hanging so thick in the air that I spasm and sneeze. It takes six of them to hold me down and fasten the manacles, and I nearly faint when they extend my right arm—the morphine must be wearing off. Everything blurs for a few seconds. I look up at the inside of the canopy over the bed, and it seems to me as if I've seen it before—seen it in my mind's eye a minute ago, in fact.

This isn't a bed: it's an altar. It used to belong to a fertility cult. It's been used for sex magic. What do I know about sex magic, and revenants, and summonings? Think!
