No, I'm afraid not. Only Quigley Quagmire appears in The Slippery Slope (book 10).
After escaping with Hector in the air, the Baudelaire orphans go to a great deal of trouble to find them. Mean while, up in the air, the Quagmire triplets, Duncan and Isadora are attacked by VFD crows which took out the balloons supporting them. As a result they were taken down to the vast unknown, making the Quagmire triplets a mystery. It is possible that Duncan and Isadora and could be dead. Also, there's a possibility that their estate,The Quagmire Sapphires, along with the fortune, will be destroyed forever and forgotten.Yes the Quagmires are triplets but Duncan and Isadora's brother, Quigley died in a fire along with the Quagmire parents.
Yes, he appears later in the series (book ten: The Slippery Slope) and becomes close with Violet, but at the end of the book he is lost.
Nope.
The book never says if they live or die.
nobody- there was never a film with those characters in
In "A Series of Unfortunate Events," Isadora and Duncan Quagmire are ultimately not saved from Count Olaf during their first encounter. They are captured and taken away, leaving the Baudelaire orphans to continue their quest to rescue them throughout the series. While the Baudelaires do make efforts to find and free the Quagmires, their fate remains uncertain for much of the story. Ultimately, they do reunite with the Baudelaires in the later books, but their journey is fraught with challenges.
no parent stays alive, quigely quagmire is the one who survived
no it is said that they were not talking about the Baudelaire's house fire but actually the quagmire's house fire and the survivor was quigley quagmire the 3rd triplet assumed dead.
My opinion would be the unfortunate events
The book "A Series of Unfortunate Events: The Slippery Slope" by Lemony Snicket has around 337 pages in the hardcover edition.
