It will be a day of investigations for the residents of Port Charles as they attempt to uncover the truth. On the Monday, Nov. 5 episode of “General Hospital,” Carly confides in Jason as Sonny learns about Margaux’s next move.

In the promo for the ABC soap opera, Carly (Laura Wright) tells Jason (Steve Burton) there’s a mystery locked up in Ferncliff, and she’s going to solve it. “General Hospital” spoilers reveal Carly leans on Jason.

In the previous episode, Carly discovered Mary Pat’s (Patricia Bethune) severed head in a barrel of apples and became a suspect in her murder case. Ryan (Jon Lindstrom), who was posing as his twin brother Kevin, told Chase (Josh Swickard) and Jordan (Briana Nicole Henry) that Carly didn’t like Mary Pat while she was locked away at Ferncliff and was heard threatening her.

After Carly denied murdering Mary Pat, Jordan suggested she may have had Sonny (Maurice Benard) do it for her. Sonny told Jordan she would have to find another suspect, but it appears Carly will start her own investigation into the murder.

Although Jason witnessed the abuse Carly suffered while under the care of Mary Pat at Ferncliff, chances are he doesn’t think his old friend killed the nurse.

Carly wasn’t the only patient who disliked Mary Pat and is just one of many people that had a motive to kill her. Will Jason help Carly uncover what’s really going on at Ferncliff, or will he talk her out of it?

Elsewhere in the ABC promo video, Sonny tells Margaux (Elizabeth Hendrickson) that she has no idea what she is going to find. “GH” spoilers reveal Margaux starts an investigation.

After Sonny learned Margaux’s mother ordered her father’s murder, he decided to bring the evidence to the district attorney so she would stop trying to link him to the crime.

It appears Sonny isn’t pleased with the way Margaux responds to the new evidence, and the two plan to take a closer look at the past. Will Sonny and Margaux team up to figure out the truth about her father’s murder?

“General Hospital” airs weekdays at 3 p.m. EST on ABC.
