four o'clock
They are to meet at one o'clock tomorrow . That 's the first matter to report . The second is that Marston is spying around the French Embassy . He has walked up Sixteenth Street frequently since four o'clock , and never once glanced at the big marble mansion when he thought anyone was looking . His eyes were busy enough other times . Also he visited , after dark , Paublo 's Eating-House in the Division , and had a talk with Jimmy-the-Snake -- a professional burglar of the best class . We are watching The Snake , of course .
