When Did You See Her Last?

Before he wrote 'A Series of Unfortunate Events', before the Baudelaires became orphans, even before the invention of Netflix, Lemony Snicket asked all the wrong questions. Four to be exact. This is the account of the second question.
In the fading town of Stain'd-by-the-Sea, young apprentice Lemony Snicket has a new case to solve when he and his chaperone are hired to find a missing girl.
Is the girl a runaway? Or was she kidnapped? Was she seen last at the grocery store? Or could she have stopped at the diner? Is it really any of your business?
In the tradition of great storytellers, from Dickens to Dahl, comes an exquisitely dark comedy that is both literary and irreverent. You'll laugh only if you find humour in gothic and mysterious things involving detectives and crime solving.
Lemony's other literary outings in 'A Series of Unfortunate Events' have sold 60 million copies worldwide and been made into a Hollywood film starring Jim Carrey and a Netflix series starring Neil Patrick Harris. These regrettable developments mean that millions of fans have found out about the dreadful plight of the Baudelaire orphans, but you do not have to. You have been warned.
Have you read all four mysterious titles in the Wrong Questions series?
'Who Could That Be at the This Hour?'
'When Did You See Her Last?'
'Shouldn't You Be in School?'
'Why is This Night Different from All Other Nights?'
Author Lemony Snicket was born before you were and is likely to die before you as well. He was born in a small town where the inhabitants were suspicious and prone to riot. He grew up near the sea and currently lives beneath it. Until recently, he was living somewhere else. He is a broken man, wracked with misery and despair as a result of writing 'A Series of Unfortunate Events'. He spends his days wandering the countryside weeping and moaning and his evenings eating hastily-prepared meals.
Artist Seth has portrayed suspicious circumstances and shady characters in much of his work. He is a multi-award-winning cartoonist, author and artist, whose works include Palookaville and Clyde Fans.

Lemony Snicket was born before you were and is likely to die before you as well. He published his first book in 1999 and has not had a good night's sleep since. Mr Snicket is the author of quite a few books, all dreadful, and has been falsely accused of many crimes, all falsely. Once the recipient of several distinguished rewards, he is now an escapee of several indistinguishable prisons. He is widely regarded as one of the most difficult children's authors to capture and imprison. There are thirteen books in the A Series of Unfortunate Events, which should be avoided at all costs. He has also written the mystery series 'All the Wrong Questions'.
To his horror and dismay, he has no wife or children, only enemies, associates, and the occasional loyal manservant. Until recently, he was presumed to be 'presumed dead'. Instead, this 'presumed' presumption wasn't disproved not to be incorrect. Most things written about him are not true, but this is.
