Nhibernate : Inner join Sql statement to Nhibernate ORM

Question

I have 2 tables

Employee

Id	FirstName
1	chris
2	alex

Salaries

EmployeeId	Salary
1	1000
2	2000

and the following SQL statement that i would like to translate it to Nhibernate syntax

SELECT S.Salary
FROM Salaries S INNER JOIN Employee E
ON s.EmployeeId = E.Id
WHERE E.Id = @id

What i have done so far:

public ActionResult Details(int id)
        {
            using (ISession session = NHIbernateSession.OpenSession())
            {
 
                var employees = session.QueryOver<Employee>().List();
                var salaries = session.QueryOver<Salaries>().List();
 
                return View(??);
            }
        }

What i would like is to get the Employee's salary based on their ID that is referenced to the Salaries table
