A Good Girl's Guide to Murder ending: Why didn't Becca help Andie while she was dying? Explained

Andie Bell's murder mystery in A Good Girl's Guide to Murder has been finally solved, thanks to Pipp 'Pip' Fitz-Amobi (played by Emma Myers), who decided to prove Sal Singh (Rahul Pattni) innocent and discover who actually killed the 17-year-old Andie (played by India Lillie Davies).

Andie Bell was a former student in Pip's school, who went missing five years before Pip decided to solve her case as an extended project qualification. Since childhood, Pip was curious about the Andie Bell case and knew that the truth was hidden inside a web of lies.

As Pip began her quest, she was accompanied by Sal's younger brother Ravi (Zain Iqbal), who also wanted to find the truth. However, little did they know that it wouldn't be an easy task to unmask the killer, who cleverly escaped the crime.

A Good Girl's Guide to Murder has a total of six episodes, each taking Pip one step closer to confronting Andie Bell's killer. Everyone in the town believes that Sal killed Andie and committed suicide until Pip finds that he was framed and killed.

Throughout the episodes, Pip receives threatening notes and messages, alarming her to stop digging for the truth. However, Pip doesn't stop and finds out unexpected truths about Andie Bell, Elliot Ward (Mathew Baynton), Max Hastings (Henry Ashton), and the real murderer.

In episode five, Pip discovered that Andie was sleeping with her English professor Elliot Ward, a suspect in the case. However, the two parted ways after Andie fell hard for Sal, and started blackmailing Elliot to give her some money.

On the night Andie went missing, she and Elliot fought, and Elliot pushed her. This caused a severe injury to her head with major blood loss. However, before Elliot called an ambulance, Andie ran away, ensuring Elliot that she didn't die.

Andie Bell went back to her house and told her sister Becca (Carla Woodcock) that she was running away. Their father was extremely controlling, and Andie wanted freedom. However, her confession provokes Becca and she pushes her away, causing Andie to hit her head once again and die of vomiting and choking.

In A Good Girl's Guide to Murder episode six, Becca confesses that she killed Andie and that it was an awful experience watching her die. However, she didn't even try to save her sister, because she was indirectly responsible for Becca's r*pe.

Andie Bell was saving money to run away from her father by selling drugs, but she didn't know that one of her buyers Max Hastings used the substance in spiking Becca's drink and r*ped her.

Becca Bell had ill feelings for her sister due to Max, and after hearing Andie's plan to leave her alone, she couldn't stop herself from pushing back Andie. Becca even took Pip to the deep well where she threw Andie's dead body and later tried to push Pip as well after spiking her coffee.

Well, if you think that it was Becca alone, who was blackmailing Pip through notes and texts, then you're wrong. Two people were threatening Pip to stay away from Andie Bell's case, one of whom was Becca Bell. And the other one?

It was none other than her best friend Cara's (Asha Banks) beloved dad, and their English professor Elliot Ward. He was worried that Pip would discover the truth, which would ultimately put him behind bars, not only for sleeping with Andie but also for framing Sal for the murder and eventually killing him.

Yes, Elliot is the one who killed Sal and wrote a fake confession about murdering Andie Bell. He also threatened his daughter Naomi and her friends to lie about Sal leaving the party early, which could make him the prime suspect in Andie's case.

In the end, Pip and Ravi share a romantic moment, marking the beginning of their new relationship. Pip then confronts Max Hastings and tells him that she will soon discover each of his victims whom he has ever wronged.
