On Saturday, however, there was added to the events of the season one item of great importance, which would have caused Marion no little uneasiness could she have caught more than the most superficial hint concerning it. This hint was so superficial that it consisted merely of a glimpse at the address and postmark on a letter that arrived at the house with the early mail. Marion took the letters and papers from the mail box, and as she was distributing them she observed the Hollyhill postmark on an envelope addressed in a man's handwriting to Helen Nash.
