What request does the Captain make of Nick in Chapter 13?

In Chapter 13, the Captain wants Nick to give Lorne Lutch a bribe to gag him while he is in California. Nick is concerned about how Lutch will react, but the Captain argues that they are just going to give the man a briefcase full of money with no strings attached. He believes that such a gesture - if kept quiet - will persuade Lutch to quiet down in his last months of life.
