Calling Mr. Callaghan

WHEN Callaghan came into the office, Effie Thompson stopped typing. She said: "Good morning, Mr. Callaghan. There have been a few telephone calls, and your letters are on your desk."
Callaghan said: "Right, Effie. Has Fallon or Craske been through?"
She shook her head. Callaghan went into his office. She followed him with her notebook.
She said: "You're expecting a call from Fallon or Craske? If either of them come through while you're out what shall I do about it?"
Callaghan said: "There's nothing you can do, Effie. Both those birds ought to be pretty scared by this time—both of them or one of them."
She said: "You don't know which one was really responsible for that fraudulent claim?"
