The formaldehyde, for that is what the liquid must be, had done its job. There was also clearly some way in which the bubbling injections of gas were allowing the ghost to still form a noncorporeal self while not losing too much flesh to decomposition. Alexia was caught by the genius of the invention. It was one of the great trials of ghostly employment, that specters would stay sane only so long as their bodies could be preserved, but that they could not form a tether and apparition if that body was immersed fully in a preservation liquid. Madame Lefoux had invented a way around this conundrum by having air bubbling through the formaldehyde in enough quantity to permit a tether, while allowing the flesh to stay submerged and preserved. No wonder Formerly Lefoux had enjoyed such a long afterlife.

But even such ingeniousness as this, the height of scientific breakthrough, could not save a ghost in the end. Eventually the body would decay enough so that it could no longer hold the tether; the ghost would lose cohesion and succumb to second-death.

Alexia thought she might mention this tank to BUR. They would probably want to order a few for their more valuable spectral agents. She wondered if the gas injections had something to do with the explosive nature of Formerly Lefoux’s poltergeist state. In any event, the tank’s work was completed. Alexia had to devise a way inside.

The screams were now deafening. Formerly Lefoux’s misty body parts were centering on Alexia, attaching themselves to the exposed skin of her arms, face, and neck, like body part burrs. It was repulsive. Alexia tried to brush them off, but they merely transferred to her wrist.

There seemed no way into the tank. Madame Lefoux had never intended to open it once it was built.

Lady Maccon was getting frantic to stop the screaming. She was also becoming increasingly aware of time wasted. She must get out of the contrivance chamber and stop Madame Lefoux’s mad scheme to build a monster to kill the queen. Why would Genevieve, of all people, want to do such a thing?

Desperate, she flipped her parasol, hefted it as far behind her back as her condition would allow, and swung it around with all her might. She hit the side of the glass tank with the hard pineapple-looking handle. The tank cracked and then broke, spilling the yellow fluid and with it a strong, suffocating scent. Lady Maccon backed away hurriedly, lifting her ruffled skirts out of the toxic liquid. Her eyes began burning and watering. She coughed as the sensation moved to her throat, and she tried to breathe in shallow gasps. Luckily, most of the liquid was absorbed quickly by the hard, compact dirt of the contrivance chamber floor.

The body inside flopped over and against the cracked side of the tank, one hand dangling out through the broken glass. Quickly, Alexia tugged off her glove and stepped up to it. She touched the cold dead hand once, flesh to flesh, and just like that, it was over.
