"Indeed?" he murmured.
"Look here," said Carrington with a candid smile, "let's put our cards on the table. You know my business?"
"Are you a detective?" asked the lawyer.
Mr. Carrington smiled and nodded.
"I am; or rather I prefer to call myself a private enquiry agent. People expect so much of a detective, don't they?"
Simon grunted, but made no other comment.
"In a case like this," continued Carrington, "when one is called in weeks too late and the household broom and scrubbing brush and garden rake have removed most of the possible clues, and witnesses' recollections have developed into picturesque legends, it is better to rouse as few expectations as possible, since it is probably impossible to find anything out. However, in the capacity of a mere enquiry agent I have come to pick up anything I can. May I smoke?"
He asked in his usual easy going voice and with his usual candid smile, and then his eye was arrested by an inscription printed in capital letters, and hung in a handsome frame upon the office wall. It ran:
"MY THREE RULES OF LIFE,
1. I DO NOT SMOKE.
2. I LAY BY A THIRD OF MY INCOME.
3. I NEVER RIDE WHEN I CAN WALK."
