  On the following day Mrs. Kent went into the bed-room; and laid a reticle, which contained the money, upon her bed; and afterwards returned into the sitting-room; leaving the door between that and the bed-room open. After she had remained in the sitting-room about five minutes, she sent Miss S. for the reticle; and it was not to be found.
