Though little detail is known about Jacques, he seems to have been a very active volunteer. Before his death, Jacques worked briefly for The Daily Punctilio, for whom he wrote an article proving that the Royal Gardens Fire was arson. At one point, he worked for Captain Widdershins on the Queequeg, and for Anwhistle Aquatics's Voluntary Fish Domestication program. When Café Salmonella began using these fish in their dishes, he and his siblings participated in a fight against the restaurant, known as the Snicket Snickersnee, but to no avail. After the destruction of Anwhistle Aquatics, Jacques wrote another article for The Daily Punctilio, entitled "Verifying Fernald's Defection," which claimed Fernald was responsible for the fire.
He later met Quigley Quagmire at the former home of Dr. Montgomery Montgomery while doing research in an attempt to track the Baudelaire orphans; why he was tracking them is unknown, though it is possible that Lemony asked him to do so. Jacques also stayed for a brief period at Lucky Smells Lumbermill, while investigating the death of Dr. Georgina Orwell. He seems to have been a good friend of Jerome Squalor, having urged him by letter both to buy the penthouse at 667 Dark Avenue and not to marry Esmé Squalor, although the later letter did not reach Jerome.
Jacques appeared briefly in The Vile Village, where he was mistaken for Count Olaf by various citizens of the Village of Fowl Devotees. Before he could be burned at the stake, he was murdered by the real Count Olaf, who blamed the Baudelaires for the murder. However, before Jacques was killed, he tried to tell the Baudelaires the true meaning of V. F. D., saying, "I work for the volunteer...".
At some point before his death, he and Lemony lost contact and Jacques remained close to Kit.

- ↑ The Snicket family goes in alphabetical order (with the exception of Jacob Snicket, who was known as something else to his bridge partner); so, if Jacques was YOUNGER than Lemony, he would not have Jacques as a name; his name would begin with K or L, and Lemony's name would begin with a J in his place; this means he must be OLDER than Lemony.

- ↑ Lemony Snicket: The Unauthorized Autobiography quotes a letter from Jacques Snicket to Lemony Snicket that says, "I feel, Lemony, as if we are drifting away from one another, as if one of us is on the ground and the other is in some wondrous device, floating away into the sky, like that self-sustaining hot-air mobile home 'H' is always talking about building," indicating that Lemony and Jacques, at one point in their lives, lost contact, but it is not stated as to whether they reunited before Jacques died.
