I Remember It Well - S3.E1

Alexander's appraiser discovers the fake replicas of a priceless set of jewels because he arrived late due to the weather. Inspector Metti tells Alexander and Peter that he suspects that the burglar is none other than Nikki Beaumont because this heist has all her hallmark signiture. The good inspector reminds Sinclair of their first case together involving 6 stolen Meitis paintings and gives him 48 hours to investigate. Unknown to anyone, a dangerous French gangster by the name of Godard hired an old pro, who is Nikki's father and mentor, to do the heist. The old pro, who was busted for the Mestis paintings, and his two masked burglars double crossed Godard by stealing the jewels a day early and fled Paris.
