While Hamilton groaned under Petra's ministrations, Matheson's body worked under the guidance of Doctor Richter. The entire apparatus looked something less than professional. Above, on a small table, rested a drip bottle containing ferric ferrocyanide, or Prussian blue dye. This was nontoxic. From the bottle a tube led into the stainless steel pressure cooker, through a hole Bernie had hand cut and then sealed. Exactly beneath the hole, a burner projected, located so that the drip from the tube would drop Prussian blue right onto the flame. The burner had its own oxygen supply, fed in before combustion took place, from a medical bottle.
Another tube led from the top of the stainless steel vessel to a stoppered glass beaker. The tube extended nearly to the bottom of the beaker. Above the level of the end of that tube was the lye he'd obtained at the bakery. A tube above the level of the lye led out through the stopper and to another beaker containing a slurry of charcoal and water. A further tube from that last beaker led to a just- slightly-opened window.
Matheson lit the burner and started the Prussian blue drip.

Petra lifted her head away.
She looked up into Hamilton's eyes, hoping to find that she'd pleased him. Instead she saw a look she had never seen before on any man's face. She really didn't know what it meant.
Nor did Hamilton explain. He just pulled her up along the bed, toward the pillow. Then he spread her legs, and took a position very similar to the one she had held until a few moments before.
This wasn't exactly new to Petra, after all, she and Ling had been lovers for years now. But none of her clients had ever shown any interest.

Bernie was a mere observer as Richter stopped the drip and then turned off the burner. Almost immediately, gaseous bubbles that had been rising in both of the beakers stopped. In one beaker, bathed in lye, was a layer of whitish crystals. He shared minds, to a degree, with Richter and knew that these were hydrogen cyanide, harmless in the current form. The crystals Richter separated out, storing them in one of the larger glass jars. The used lye was thrown away and replaced. The charcoal-water slurry likewise went down the toilet and a new batch was added to the second beaker.
Bernie tried. Nonetheless, the potentially deadly bubbles arising on the second batch reminded him continuously that this chemist operating his body from thousands of miles away held his life in his hands.
And they were going to be at this all night.
