"Friday, 1st March.--Abel Death discharged by Samuel Boyd. He pays a visit to Catchpole Square at about ten o'clock to beg Boyd to take him back into his service. Reginald's two visits to the house, the first in the afternoon, the second late at night, hour unknown. In his haste to get away on the second occasion he drops in the passage the key of the street door. Samuel Boyd murdered. Query--Did Abel Death and Reginald meet? Would it be advisable, when Reginald is in his right senses, to ask him about this?

"Saturday, 2nd March.--Mrs. Death goes to Catchpole Square to obtain news of her husband. Unsuccessful. Good reason for it. Dead men tell no tales. Reginald back in his lodgings, in bed, delirious. The events of the previous night being fresh in his mind, it is likely he raved about them. Query--Who attended to him? His landlady. Did she hear anything that would furnish a clue, and will this occur to her when the murder is discovered?

"Sunday, 3d March.--Mrs. Death repeats her visits to Catchpole Square. Same result. Same reason for it.

"Monday, 4th March.--Mrs. Death continues her visits to Catchpole Square.

"Tuesday, 5th March.--The day of the great fog. My conversation with Uncle Rob in the police station. Mrs. Death and Gracie are brought in. Her story. Florence leaves home secretly to nurse Reginald. Fearing that he is dying, and gathering from his ravings that he wishes to see his father, she goes to Catchpole Square after midnight. She is seen by the police and drops her handkerchief, which Constable Pond picks up. My conversation with Applebee. He tells me that Pond has a room to let. I reconnoitre Samuel Boyd's house, and determine to force an entrance next night. Only one way of getting in, by means of rope and grapnel.

"Wednesday, 6th March.--At the police court with Mrs. Death and Gracie. I write par. for 'L. B. B.' I take lodgings in Pond's house, and obtain possession of Florence's handkerchief. Visit Aunt Rob, and learn particulars of Florence's flight. I purchase rope and grapnel. I visit Mrs. Death. No news of her husband. Make the acquaintance of Dr. Vinsen. He gives Mrs. Death two pounds. Why should he be so generous? At one in the morning I get over dead wall, and into Samuel Boyd's house. Discovery of the murder. Find Samuel Boyd's written accusation of his son. Pocket it. Find Reginald's key to street door. Pocket it. Things look black.

"Thursday, 7th March--Visit Aunt Rob. Receive letter from Florence. Go to her. Fetch Aunt and Uncle Rob. Leave them together. Things look blacker."

Replacing the memorandum book in his pocket he became conscious that he was being observed. Looking up he saw the sleepy eyes of Dr. Vinsen fixed upon him.

"My dear young friend," said the doctor, with an amused smile, "I have been observing you for quite three minutes, and wondering what engrossing task you were engaged upon to make you oblivious of passers-by. An effort of literature--a poem--an inspiration? I envy the literary character. So free, so untrammelled by the ordinary circumstances of our prosaic existence! It soars on the wings of imagination into fairy realms--in-to fai-ry realms. Who knows that you have not in your pocket"--he tapped Dick's breast with a light finger--"something that will open our minds to noble truths? Who knows--who knows?"

"I know," said Dick. "If an account of how many socks, and collars, and handkerchiefs I have sent to the wash will elevate mankind I am sure I have no objection."
