midnight
The Doctor stood by his electric runabout , for half an hour or more . Then , the Doctor feeling that a false alarm had been spread , whirred up the hill . The younger men stayed on Market Street . They left it long after midnight , deserted and still . As the watching party broke up , a telephone message from the offices of Calvin & Calvin winged its way to Sands Park , and from the shades there came silently a great company of automobiles with hooded lights . One separated from the others and shot down into the Valley of the Wahoo . The others went into Market Street .
