Mr. Maurice Greywood, the talented young artist who returned from Paris the beginning of last winter, has disappeared, and grave fears for his safety are entertained. He was last seen in his studio, 188 Washington Square, early on Tuesday, August 8th, by Mrs. Kate Mulroy, the janitress. Ever since the young artist moved into the building, Mrs. Mulroy has taken complete charge of his rooms, but, owing to a disagreement which took place between them last Tuesday, she has ceased these attentions. Yesterday evening, while looking over a copy of the _Bugle_ of the preceding day, Mrs. Mulroy came across the portrait of the unknown man whose murdered body was discovered under very mysterious circumstances in an unoccupied apartment of the Rosemere, corner of ---- Street and Madison Avenue, on the preceding Thursday. She at once recognized it as bearing a striking resemblance to her lodger. Thoroughly alarmed she decided to investigate the matter. After knocking several times at Mr. Greywood's door, without receiving an answer, she opened it by means of a pass-key. Both the studio and bedroom were in the greatest confusion, and from the amount of dust that had accumulated over everything, she concluded that the premises had not been entered for several days. Her worst fears being thus confirmed, she hastened at once to the Morgue, and requested to see the body of the Rosemere victim, which she immediately identified as that of Maurice Greywood. Strangely enough, the police throw doubts on this identification, although they acknowledge that they have no other clue to go on. However, Mrs. Greywood, the young man's mother, has been sent for, and is expected to arrive to-morrow from Maine, where she is spending the summer. The people at the Rosemere are still foolishly trying to make a mystery of the murder, and refuse all information [etc., etc.]. TO DR. CHARLES K. FORTESCUE FROM DR. FREDERIC COWPER, BEVERLEY, L. I.
