have them occasionally. Sometimes they last for days. This one is
a low one. It will lift presently. Then you will see the sun. Have

"My dear sir"--this same slow articulation--"I have never seen
your sun nor any other."

voice harsh or testy. Rather was it soft and polite, of one merely

man come? A detective has a certain gift of intuition. Though on
the face of it, outside of the man's personality, there could be

pulled back the door which had been closed behind them and re-
entered the boat. When he returned the boat had arrived at the

It was a chance question.

"No, to Berkeley. I take a train here, I understand. Do all the
trains go to Berkeley?"
