References: (1) and (2) “She was enamoured with the prospect of a good night’s sleep. Red bullets filled with Isabella dust. The tried and true thing that turns a dyed-in-the-wool insomniac into a lead filled rag doll by obliterating all senses, including that of time. The only solution she relied on was her closely guarded bottle of Seconals”. It’s a sad reality but she is turning into an addict. Slowly. Time will tell whether she snaps out of this nonsense or not, but she can’t rely on pills forever.”

(3) “The Koestlers topped themselves with Isabella dust, a less common but relevant reference to the barbiturate Tuinal that was found at the scene of the tragic double-suicide.”
