her. She could have killed him then and there.”
“Caroline.”
“I’m not saying she _did_, James. I’m saying she _could_ have done. As a matter
of fact, though Flora is like all these young girls nowadays, with no veneration
for their betters and thinking they know best on every subject under the sun, I
don’t for a minute believe she’d kill even a chicken. But there it is. Mr.
Raymond and Major Blunt have alibis. Mrs. Ackroyd’s got an alibi. Even that
Russell woman seems to have one—and a good job for her it is she has. Who is
left? Only Ralph and Flora! And say what you will, I don’t believe Ralph Paton
is a murderer. A boy we’ve known all our lives.”

“Let us take a man—a very ordinary man. A man with no idea of murder in his

never been called into play. Perhaps it never will be—and if so he will go to
his grave honored and respected by every one. But let us suppose that something
occurs. He is in difficulties—or perhaps not that even. He may stumble by
accident on a secret—a secret involving life or death to some one. And his first
impulse will be to speak out—to do his duty as an honest citizen. And then the
strain of weakness tells. Here is a chance of money—a great amount of money.
