The Quagmire Triplets, like the Baudelaires, are orphans whose parents perished in a fire that destroyed their home. Also, the Quagmire triplets are good friends with the Baudelaires.
The triplets each have a notebook that their parents gave them, and an associated skill that they use the notebook for. Duncan has a dark green notebook which he uses to record his journalism, Isadora a pitch black one that she writes poetry in, and Quigley had a purple one in which he practices cartography. With information about Olaf and his secrets.
The Quagmires are also rivals of Count Olaf because of their fortune, just like the Baudelaires.
Duncan and Isadora the tripletsEdit
In The Ersatz Elevator, Duncan and Isadora are discovered locked in a cage at the bottom of an unused and apparently pointless elevator shaft at 667 Dark Avenue, the address of the Baudelaire children's latest guardians Jerome and Esmé Squalor. They are described as having a 'haunted look' about them. They know little about Olaf's current scheme, but they are able to reveal that he plans to smuggle them out of town. The Baudelaires return to their home in the penthouse to prepare blowtorches to free the two triplets from their cage, but find them gone when they return to the bottom of the shaft; the removal of their cage exposes the shaft's true purpose as a secret tunnel. At the end of the book, Olaf, Esmé and the Hook-Handed Man successfully escape with the Quagmires, who had been hidden inside a red herring statue.
Duncan and Isadora make their last appearance in The Vile Village (though they are referenced regularly for the rest of the series). The village caretaker Hector, with whom the Baudelaires live, upon hearing about the Quagmires, gives to them a scrap of paper upon which is written a couplet which they recognize as Isadora's poetic style. Hector says that he found the paper at the bottom of the Nevermore Tree, where the crows that populate the village roost every night. More couplets are found at the bottom of the tree as the story unfolds and the Baudelaires soon discover the couplets, when put together, reveal where the two triplets have been imprisoned within the village. The Baudelaires eventually free them and they are pursued along with the Baudelaires by the villagers to the outskirts of town. Once there, Hector appears in his self-sustaining hot-air mobile home. Duncan and Isadora climb onto the home safely, but the Baudelaires are thwarted in their attempt to do the same by Esmé Squalor, disguised as Officer Luciana, using a harpoon gun. The triplets throw their notebooks to the Baudelaires and beg them to read their notebooks to discover the secret of V.F.D, but Esmé also destroys the notebooks using the gun. Duncan and Isadora fly away in the home with Hector, safe from Olaf's clutches. Their now fragmented notes prove to be of some assistance to the Baudelaires in learning more about V.F.D, Olaf and their own connections to the organization.
Isadora and Duncan were attacked by V.F.D. eagles, which took out the balloons supporting them, just as they met up with Quigley. As a result, they were sent down, taking out the Queequeg directly below them. They are taken by The Great Unknown.
At the beginning of The Austere Academy, Quigley Quagmire was thought to have died in the fire that killed his parents until Violet and Klaus Baudelaire met him in a cave with the Snow Scouts in The Slippery Slope. He and Violet clearly have some romantic interest in each other; at one point, Snicket implies that Violet and Quigley kiss (as they climb a waterfall, Violet comments on the view, which Quigley agrees it looks beautiful; however, he is looking at her when he says this, giving the reader the impression that he is saying that she is beautiful instead of the view). Snicket then decides to break off at this point and let Violet have some privacy. However, he tells the reader that, throughout the rest of their climb, they had "small, secret smiles," and, when Quigley expresses surprise that they've been climbing the whole afternoon, Violet reminds him (while giving him a shy smile) that they have not been climbing the whole afternoon. Also, when the siblings are separated from him, Violet is the only one to start weeping. As well as this, throughout the next book, Quigley is always described as "a cartographer—someone who is very good with maps, and of whom
His mother hid him in a trapdoor during the fire to protect him. He was under there for a few hours, then he found that it was a tunnel. It took him to Dr. Montgomery Montgomery's house, after the Baudelaires had been there. The house was empty, proving that the Baudelaires had already left and Dr. Montgomery was already dead. This also implies that the Quagmire house burned down after the Baudelaire mansion. Then, Jacques Snicket arrived, but left for Paltryville after researching the Baudelaires stay at Dr. Montgomery's.
At the end of the book, the Baudelaires and Quigley escape Olaf, but the icy Stricken Stream melts, and Quigley gets washed away by the current of the river into a separate tributary. He apparently survives, as he sends the Baudelaires a telegram with a hidden message in it in The Grim Grotto, telling them to go to Briny Beach. He also hides the word 'violet' in the message, which seems to have nothing to do with telling the Baudelaires where to go -- Violet suggests that he just wanted to write her name, a further implication of their romantic involvement. Violet then runs to the taxi cab, saying Quigley's name under her breath (it is earlier stated that she felt as if she had been whispering his name to herself for days), before shouting it. He is on the fire fighting side of the schism.
In The Penultimate Peril, Kit Snicket tells the Baudelaires that Quigley and Kit were planning to meet up with the three children, but he received word from his other two siblings that they were being attacked in the sky. Kit says that he stole a helicopter to help them and Hector, and would do this by constructing a huge net.
At the end of the series, Kit informs the Baudelaires that Quigley did indeed manage to meet up with his siblings, shortly before the eagles popped the balloons holding them up. Everyone inside the mobile home was sent toppling downwards, destroying the Queequeg directly below them. Duncan, Isadora, Kit Snicket, Captain Widdershins, Fiona, Phil, the Hook-Handed Man, Hector, Ink and Quigley were all left stranded in the water, before the large question-mark shaped object, The Great Unknown, appeared below them. Kit and Ink managed to escape, while everyone else wanted to take a chance with the unknown and were pulled under, to their rescue. It is unknown if they are alive or not, but in The End it is mentioned that the Quagmires are "in circumstances just as dark [...] as the Baudelaires'." Kit also mentions that the last she heard of them was one of the Quagmires calling out Violet's name. Sunny asks which sibling called it, but Kit didn't know. It is most likely that the sibling who called out Violet's name was Quigley.
Quigley's first name may be a reference to Lillian Fox Quigley, author of The Blind Men and the Elephant, a children's book based on a poem of the same name discussed in The Penultimate Peril.
