The Case with Nine Solutions · Chapter
Excerpts from Sir Clinton’s Notebook explained
Sir Clinton Driffield reviews the evidence and develops a hypothesis about the murders.
What happens
Sir Clinton Driffield reviews the evidence and develops a hypothesis about the murders. He notes the breakup of the Silverdale ménage, Hassendean's interference with coffee service, Mrs. Silverdale's dazed appearance, and the two shots that wounded Hassendean not fired in Ivy Lodge. He considers the disappearance of Mrs. Silverdale, Hassendean's dying words, the murder of the maid at Heatherfield, the ransacked drawer, the envelope fragment dated 1925, and the old dance programmes. He concludes the affair is not a simple triangle tragedy, pointing to drugging, the Heatherfield burglary, and Hassendean's phrase 'Caught me...' He suspects Dr. Markfield, noting his reluctance to testify against Silverdale, his knowledge of the case, and his access to hyoscine. After the discovery of the bungalow tragedy, he deduces Hassendean drugged and accidentally killed Mrs. Silverdale, then shot her body to mislead. He identifies hyoscine as the poison, explaining Hassendean's dosage error. He considers Miss Hailsham as 'Justice' but finds it problematic. He notes Markfield's car accident alibi and the man seeking reward at the police station. He suspects Markfield of the Heatherfield burglary to retrieve letters, and notes the fake photographs point to Markfield. He lists points against Markfield, including his intimacy with Mrs. Silverdale, his movements, and his access to a microphotographic camera. He concludes strong suspicion but no proof, and decides to bluff. After the explosion at Markfield's house, he notes Markfield died, and the case ends as a draw.
Themes in this chapter
Murder and Investigation
Sir Clinton systematically analyzes clues, develops hypotheses, and evaluates suspects in the double murder case.
Deception and Secrecy
Lies, hidden relationships, and secret letters are central; Silverdale lies about his alibi, and Markfield's past with Mrs. Silverdale is concealed.
Science and Poison
Hyoscine is identified as the poison; Hassendean's dosage error due to metric/apothecary confusion is explained.
Identity and Appearance
The ring's initial B, the fake photographs, and the use of disguises (amateur theatricals) highlight issues of identity and deception.

Key passages
“The breakup of the Silverdale ménage, with Silverdale turning to Avice Deepcar whilst Mrs. Silverdale lets Hassendean frequent her openly.”
The Silverdale household fell apart as Silverdale pursued Avice Deepcar and Mrs. Silverdale openly entertained Hassendean.
Sir Clinton notes the marital breakdown as a key clue.
“The 'dazed' appearance of Mrs. Silverdale when she left the house after coffee.”
Mrs. Silverdale looked confused or drugged when she left after coffee.
This suggests she may have been drugged.
“The two shots which wounded Hassendean at close quarters were not fired in Ivy Lodge.”
Hassendean was shot elsewhere, not in Ivy Lodge.
This exonerates Dr. Ringwood from suspicion.
“The words: 'Caught me … Thought it was all right. … Never guessed,' which Hassendean uttered before he died.”
Hassendean's dying words were 'Caught me… Thought it was all right… Never guessed.'
Sir Clinton notes that 'Caught me' suggests a different scenario than a simple love triangle.
“The murder of the maid at Heatherfield, which was clearly done by someone she knew well or she would not have admitted him at that time of night.”
The maid was killed by someone she trusted, as she let them in late at night.
This points to an acquaintance as the murderer.
“The ransacking of one particular drawer in Mrs. Silverdale’s bedroom, suggesting that the murderer had full knowledge of her private affairs.”
Only one drawer was ransacked, indicating the murderer knew exactly what they were looking for.
This suggests the murderer had intimate knowledge of Mrs. Silverdale's secrets.
