His task in Maupiti: to find another agent, named n° 12, missing in action.

Tilt: And did he find out?
J.L.: Yes! That missing agent was none other than Lucie. I made this discovery by comparing two photos, one of a soldier into firing position in Chris' file, the other one of Lucie and Juste. In both photos, the soldier and the woman wore the same bracelet, a bracelet I discovered later in Roy's cabin. Everything fitted together perfectly. A brunette by nature, Lucie wore a blonde wig so that she would not be recognized. Was she here to expose the arms trade? Probably.

Tilt: But how do you explain Juste's death? It also seems that he had become taciturn very suddenly.
J.L.: Juste certainly understood that Lucie was dead when he picked up the wig in his nets. Sue confirmed to me that "Juste caught a funny pack of yellow algae" and that "Roy was watching him". Juste got scared. He preferred to keep quiet and started running away from everyone, even Anita who loved him though...

Tilt: Do you know how this crime unfolded?
J.L.: I was able to piece the facts together, based on simple inferences. Juste's body was found at 7 a.m. at the pier. But his medallion was caught in a net at the northern beach. So the assassin killed Juste at his home, about 1:30 a.m. He then dragged the body to the beach and threw it into the water. The corpse drifted to the pier. As for the culprit, it is Roy, of course. First clue, Roy was unaccounted for on the island throughout this period. But above all, I discovered a diamond at Juste's house, next to the window. Everybody told me it belonged to Roy. He denied this fact, but I could see that the other diamond Roy had in his cabin was no longer there. So...

Tilt: But why didn't the murderer recover, once his crime had been committed, the only evidence that could incriminate him?
J.L.: Roy had locked the door of Juste's house, probably to stop my investigation. Unfortunately for him, he lost the key to the pier. Rather than embarrassing me, it brought even more strength to my forebodings: the fact that the key is on the pier proved that the assassin was a sailor!

Tilt: And Lucie, what happened to her?
J.L.: A body was found washed up on the southern beach. As everyone identified it as poor Mary's corpse, I soon realized that it was Lucie, disfigured. Like Juste, she had drifted from the northern to the southern beach. She couldn't have drowned, as she was an excellent swimmer. The reality was much more sinister. Roy was responsible once again for the crime, he who had unmasked this secret agent and became afraid that she would reveal his trafficking.

Tilt: The inhabitants of the island said that gunshots were heard... Yet Juste got his throat cut!
J.L.: The gunshots were aimed at Chris. Why? Sue said recently: "Chris asked me a lot of questions about Maupiti..." Chris was getting too embarrassing and he was the target of a failed attack. It was Roy who lured the victim to the southern beach. It was the Lady in Black who was holding the gun. From then on, I confess that I was afraid that something would happen to me. Two murders and one attempt, the climate was getting unwholesome. We had to be extra careful and find Mary as soon as possible.

Tilt: You probably had to go back to the study of the documents discovered previously?
J.L.: Exactly. And more than anything, it was the old mechanical piano that intrigued me the most. Maguy told me that "the piano belonged to Mary and that it had been delivered by an Egyptian ship two years earlier." As for Anita, she confessed that Mary never wanted anyone to touch this instrument. Mary's distrust and the discovery of the scores in her hiding place proved to me its importance in solving the enigma. The mechanical piano offered a choice of fifteen pieces. Among them were the twelve titles on the list discovered at Mary's room. But two more important discoveries were going to put me on the trail. First, I discovered an ashtray, innocuous at first, which also belonged to Mary, as Maguy confirmed to me. This ashtray, the decorative element of the piano, took its place at the top left of the instrument. Second discovery, the foot of the piano rotated and sounded like a trigger in the device. All I had to do was operate the ashtray to open a secret compartment. In this cache, white sheets, and a sheet covered with characters. I suddenly understood: the piano was used to print secret messages, messages undoubtedly related to the drama i was trying to elucidate! Satisfied with this discovery, I replaced all the elements as I had found them.
