'' `` She did n't show up , but telephoned again some time round four o'clock explaining that she had been in a taxicab accident in the Park and lost her way but finally got home -- that is , to her hotel , the St. Simon . She said the necklace was safe -- did n't mention the hat -- and asked me to call for it at noon today . I said I would , and I 'm by way of being late now . Doubtless she can explain how the hat came to you this way . ''
