Then Vic driving back to Chicago and thinking about Mrs Grafalk’s remark. How could Clayton have helped Grafalk? Suddenly, she saw the whole thing and had an idea where Clayton Phillips had been murdered. After that, she went into the Ajax Insurance Company building and asked to see the person dealing with the Lucella. Roger Ferrant had come over from London to deal with it. Vic asked him some information about the accident to the Lucella. What’s happening to the ships on the Great Lakes since the accident at the Poe Lock? Can ships still get through? He explained that ships can still use the other locks but the biggest ships are shut off from the upper lakes for a year until the Poe is fixed. She asked him that How profitable is the Grafalk Steamship Line? He said that you go through the worker’s insurance files. Then she began going through the files and it became clear that each year it cost Grafalk about a hundred and twenty million dollars to run the Steamship Line and that for the last five years his ships had made no more than a hundred million dollars a year.
