## Key lines

> You remember how Roger Tichborne’s mother identified Arthur Orton as her son, and stuck to it through thick and thin. Hallucinations of that sort do occur.

Sir Clinton compares Miss Fordingbridge's identification of the claimant to the Tichborne case, suggesting that such mistaken identifications can happen due to wishful thinking.

_Used to cast doubt on the reliability of Miss Fordingbridge's identification._

> Many murderers are most amiable persons—Crippen, for example. ‘A fair field and no favour’ is the only motto for a conscientious detective.

Sir Clinton argues that personal likability should not exclude someone from suspicion, citing the example of the amiable murderer Crippen.

_Defends his impartial approach to suspecting even those he likes._

> Suppose the claimant was an impostor, and see where that leads you. ... On the other hand, suppose the boot’s on the other foot. Assume that Paul Fordingbridge had some very strong reason for wishing to retain control over the funds.

Sir Clinton presents two competing theories: either the claimant is a fraud, or Paul Fordingbridge is a dishonest trustee, showing the dual possibilities in the case.

_Illustrates the symmetrical motives of both parties in the inheritance dispute._
