From Memoirs (o)f Death, chapter: Inscription
Lady Evelyn stick the notes she’d received from Trumbo all across the wall in her workshop on that night in February 1979. She carefully put the bottle down on the table and opened a book she received from Leo. Important parts on notes were underlined - first by Trumbo and now by her, and book was too valuable to be marked at all. These pages were a true pieces of art, intertwined with death and vanity. She had already tabulated exactly how many times and who had used the medicine so far.
Of course, I knew it also; I was there each time it had happened.
By now, the Ten also knew the way to summon me. They thought they had dominion over me, but I am not that easily controlled. Their secret was largely kept safe all those years. But enough had slipped out by accident or on purpose. There was some group who were hunting them one by one, aware of their forbidden knowledge. Book from Leo is stolen from them. Evelyn didn't know who was the real mastermind behind everything, but she was well aware of the Cult they were using as a front for dirty jobs. She called that organization: “The Group.”
The Ten had also already discovered that medicine worked on only one person at the time: if anyone else took the concoction, the effect it had on the previous person would start fading away slowly over the years to come.
On one of Trumbo’s pages, Evelyn found notes from the meetings where the Ten had argued. Their thoughts and paths had started to differ. They were split between those who wanted the secret to die along with them and their physical bodies - as they expressed the will to be cremated in order to destroy the evidence - and another cadre who wanted to donate their bodies to science for further medical research.
Evelyn was disappointed that during all this time no one had managed to reverse the process of aging. They could not make someone young again, just pause the slow march toward my visit. Curing serious and deadly diseases was something her father saw as the ultimate use. She had a different dream.
There were also numerous notes on cases where the medicine hadn’t worked. Usually these were individuals suffering from heart disease or brain ailments - people too close to my door to save. Luckily that didn't apply to her. But the Book have it's own secrets and it was a time to decode them.
