Flawless, except for, well everything....so, I guess flawless is the wrong word....
1. -Why would her master try to summon a dead djinni that he thought was dead?
2. -Nathaniel is a meticulous, thorough young man, but even he didn't try to summon Bartimaeus when he thought Bart was dead/severely wounded.
3. -Some masters bind spirits to work for them indefinitely, but most just summon spirits to do a few tasks and then they are done for the day.
*Not only is it more difficult, taxing to create the complex pentacle bindings for indefinite servitude, but also remember that most of the spirits summoned for the Golem hunt were Just summoned for that. These weren't constant servants to always have on hand, like Bartimeaus or that green monkey thing that worked for Tallow. Queezle and the rest were hastily summoned just for this golem hunt.
4. +Queezle was probably only bound to service for a few days or for the specific task. I think I remember the orders the djinni had were something like: "Look for the Golem. If you see it, then alert the others. Then try and follow it."....In Queezle's mind: "Meh, I tried. Job complete. I'll do better next time. Peace out, Earth!"
*And the fact that the Golem soon died makes this even more likely, I believe. Queezle's initial summoning/orders DEFINITELY were about the Golem. Once the Golem died, her task was fulfilled.
5. -About her Master dying....There is actually a pretty good chance that Queezle's master died shortly after her "death". There were 2 things that caused a lot of magicians, and people in general, to die: A). The rampage and killing-spree of that afrit, Honorius. This speaks for itself. And then, B). The conspiracy of the Night Police being revealed. This conspiracy and the Prime Minister's growing paranoia probably caused a lot of magicians to get executed for Treason or Suspected Treason.
6. And finally, even if Queezle just had to wait it out till her master died....meh, so what? Spirits are hundreds of years old, they could definitely wait-out a short human life-span. Though still temporarily trapped in this real, Queezle would Still have been free. Should wouldn't be in service to any magician, so Queezle would Never have to risk her life and essence fighting and doing dangerous stuff. Her essence would still get stiff and she would have aches, but she wouldn't constantly be fighting and working, which is what caused Bartimaeus to become so weak and wounded over time. Plus, Queezle would be free to do whatever she wanted, so she definitely would avoid the insanity-causing boredom that plagued the trapped Honorius.
+We have no proof that Queezle is dead. No dead body, no one saw her die, there was no tiny wounded blob of wounded essence that eventually died.
+Only people who got killed by the Golem were those who attacked it like the Night Police, that one djinni, and Bartimaeus (almost got killed). Queezle was scared and didn't want to fight the golem. She would have ran and quickly out-paced the lumbering clay giant.
+Her "death" remains suspicious, but the theory of her faking her death seems likely.
