Headscratchers / The Strange Case of Dr. Jekyll and Mr. Hyde

• Why does Jekyll’s will contain separate clauses for his death and his disappearance, if Hyde is his beneficiary either way? If Jekyll were unequivocally proven to be dead, that would mean Hyde is dead, too. Even if it was done so Jekyll could fake his death and continue living under the guise of Hyde, wouldn’t that be covered under the “disappearance” part of the will?
  • Jekyll might just be covering his bases. Given that literally everything about this situation is unprecedented, he doesn't actually know with 100% certainty that Hyde will die when Jekyll dies. The only way for him to know for sure that Hyde will die if Jekyll dies is for Jekyll to, well, die. Since Jekyll's not in any great hurry for that to happen, he's probably just making sure that if it should happen that way, that he'll be able to draw upon his fortune as Hyde rather than it going intestate and Hyde being left with nothing. And if Hyde dies when Jekyll dies, well, neither of them will be in a position to worry about it anyway, so no harm, no foul. Better safe than sorry.
• Was Jekyll planning on not sleeping at all? He says in his final confession that the transformations got so out of control that he could only wear his own face for a short time after being dosed up on the drug and that if he slept or dozed off at all, he would turn into Hyde, hence why he secludes himself from the world and “condemns himself to sleeplessness”. Yet he also says that “my punishment might have gone on for years” if it weren’t for the issue of the impure salt making recreation of the serum impossible. Does that mean Jekyll was planning on getting by on little to no sleep for YEARS?! The longest a person has ever gone without sleep is 11 days, and that record was set decades after Jekyll’s time. Did he really think he could go without sleep for years?
