They leaved immediately the police station and went to the park.
It was Morag Mackenzie. Helen Robertson said that someone cut her throat with a knife and that the person, who murdered her, have to be left-handed.
Grant said that Mackenzie was not popular by Campbell. She had betrayed him.
The next day Logan and Grand went to Jimmie Brown, her boyfriend.
Brown said that he was the whole day at home.
Brown also told Logan about a ´main man´, someone who gives money to Mackenzie. He does not know who it is.
After the conversation with Brown, Logan thought that when they want to find the murderer of Mackenzie, they have to look into Craig Sinclair’s murder again
In the evening, Logan and Grant went to Jean Drummond, the sister of Sinclair to ask some questions about Sinclair.
She remembered that Sinclair was drunk and that he said, “I’m going to get bags of money.”
When they walked to the police station, Grant said that Drummond had committed a mistake. Sinclair has to say ´Bags’s money. In addition, Bags is an abbreviation for Baxter, Robert Baxter. Robert Baxter is an important businessperson who owns a big sports centre.
At nine thirty the next morning Logan and Grant were standing beside an indoor tennis court from Baxter. Baxter played tennis and hit the ball very hard with the racket in his right hand. The other man missed the ball completely. After the match Logan talk to Baxter. He had nothing important to say. However, when they leaved, they heard a phone conversation between Baxter and another. Baxter said, “The main man wants to speak him”. Baxter was the main man. Outside the complex, they saw a dark green Mercedes with car number RB 1.
When Logan and Grant drove to the police station, the phone rang. It is Tam MacDonald; he had seen Ronnie Campbell and is still seeing him. Campbell is on the other side of the road holding out his hat for people to put money in. MacDonald himself is at the other side of the road, looking like a tourist. They went immediately to that place, with the blue light.
When they arrived, they arrested Campbell. MacDonald explained that he had followed Campbell from Holyrood Park to this place.
The next day they went to Jimmy Brown again.
Brown said that he has not told the truth. He followed Mackenzie, to discover who the main man is. But a big, dark car picked her up and leaved. More he does not remember.
To discover some information about the first murder, Logan went to the place where the body of Sinclair was found. Suddenly, there was standing a man behind her. He smells to whisky.
He said that he had seen the murder and the murderer. The man, who killed Sinclair, was big, tall and he was wearing a suit. His car was big and dark. He does not remember the car number, but he was unusual, something like JB 007.
Logan got back to the police station. Grant told her that divers found the knife in a lake in the Holyrood Park. He was inside a plastic bag full of stones. The fingerprints on the knife were unknown. That can mean one thing; Campbell is not the murder, just like Brown. However, the fingerprints from Baxter are unknown. Only Baxter is still suspected.
The next day, some officers went to the house of Baxter, to arrest him. They were successfully, and brought him to Logan. With a trick, they discovered that Baxter was, like a good sportman, double-handed. When they compare the fingerprints on the knife, with the fingerprints of Baxter, they discovered that they are the same. After that conclusion, Baxter confessed the murders. He killed Sinclair, because he steals money from Baxter, and he killed Mackenzie, because she was a witness of the murder. First, Baxter paid her to shut her mouth and to tell that Campbell was the murderer, but she wanted too much money.
