The Murder on the Links

by Agatha Christie

“My friend, in working upon a case, one does not take into account only the things that are ‘mentioned.’ There is no reason to mention many things which may be important. Equally, there is often an excellent reason for not mentioning them. You can take your choice of the two motives.”

“Mon ami, you must make your own deductions. You have ‘access to the facts.’

“Think, my friend,” said Poirot’s voice encouragingly. “Arrange your ideas. Be methodical. Be orderly. There is the secret of success.”
