*Warning: Full spoilers for Verity ahead*

Colleen Hoover's fourth book adaptation has now hit cinemas, and with a stacked cast consisting of Anne Hathaway (in her fifth role of the year) and Dakota Johnson, Verity has shot straight to number 1 at the box office this week.

The story follows Lowen Ashleigh (Johnson), a struggling writer who relocates to a remote home to ghostwrite a book for bestselling author Verity Crawford (Hathaway), who has fallen comatose after a devastating car accident.

But when Lowen uncovers Verity's disturbing autobiography, and starts to become increasingly paranoid that Verity's condition might not be what it seems, she realises that there's actually something far more troubling under the surface of this family.

So how does it all add up? Was Verity faking everything all along? Read on for everything you need to know about how Verity ends.

Verity ending explained: What was the truth about Verity's autobiography?

Shortly after arriving at the Crawford house, Lowen finds a flash drive containing Verity’s autobiography, which of course she quickly finds herself absorbed by. However, Lowen discovers some deeply disturbing truths about her employers.

Verity has long been completely obsessed with her husband Jeremy (Josh Harnett), and after discovering she was pregnant, realised that her husband’s love for her might not be unconditional. Verity found herself resenting her children for taking her husband’s love away from her.

As a result of such hatred for her children, specifically her daughter Harper, Verity attempted to suffocate the child as a baby, hoping to pass Harper’s death off as sudden infant death syndrome. This proved unsuccessful, though, with Jeremy interrupting before Verity could go through with her plan.

Years later, when Verity took eight-year-old Harper and twin brother Crew out on the lake, Verity intentionally tipped the canoe upside down, resulting in Harper’s death by drowning. Before Verity’s autobiography ends, she writes that if her actions are ever discovered, she’ll end her own life by driving into a tree.

Lowen is understandably blown away by the contents of Verity’s autobiography, and with Jeremy and Verity’s son Crew suggesting that his mother still talks to him, becomes increasingly suspicious that Verity is not as incapacitated as she seems.

After several romantic encounters with Jeremy, Lowen shows him the manuscript, and he flies into a rage. He storms into Verity’s room and threatens to go to the police with what he has found unless she can explain herself, and in a scene that had every audience member with their mouths agape, Verity drops her façade and talks.

She was faking it all along.

Before she can explain herself, however, Jeremy has his hands around her throat. Lowen, watching everything unfold, screams at Jeremy to stop.

“You have to make it look like an accident,” she says.

Jeremy chokes his wife to death, and it’s not long after her funeral that he and Lowen have begun their own lives. Lowen is pregnant with their child, and she’s completed the book that she was hired to write – her life now suspiciously resembling that of Verity’s: the job, the husband, the kids.

While packing up to move house for their fresh start, though, Lowen discovers a letter underneath the floorboards. It’s from Verity – addressed to Jeremy. Being the busybody she is, Lowen decides to read it.

According to the letter, everything that Verity had written in her autobiography was little more than a writing . After the death of Harper – which was an accident after all, according to this letter – Verity’s editor suggested she write from a completely different perspective. Instead of revealing the actual way she felt, she’d write from the completely opposite viewpoint.

She didn’t hate her children, she wasn’t obsessed with her husband and she kill Harper.

So why was she lying about her condition?

Apparently, Jeremy had found the manuscript without the knowledge that it was just an exercise, and once again flying into a blind rage, he had attempted to kill Verity – drugging her and driving her car into a tree, just as she had written in her fake autobiography.

Verity had survived and, knowing that Jeremy would kill her, faked her coma and resulting condition to protect herself. Her plan was to eventually run away with Crew, leaving Jeremy with this letter to explain the truth.

Stunned by this new information, Jeremy walks in, and Lowen quickly hides Verity’s letter. Choosing not to say anything to him, Lowen realises that she and Jeremy very well may have murdered an innocent woman.

“Verity was a master at manipulating,” says Lowen in a voiceover as she drives with Verity’s husband and son.

But Verity innocent? Well, that’s on the audience to decide.

Verity is now showing in UK cinemas.
