[[caption-width-right:214: Off to Cornwall for some happy family time.]]

-> '''Lynley''': I have a favour to ask of you. Would you call me "Tommy" this weekend? Or even "Thomas"?
-> '''Havers''':''[shocked]'' No, I don't think so, sir.

Lynley and Helen arrive at Howenstowe, Lynley's estate in Cornwall, where his mother, Lady Asherton, lives. The purpose of their visit, of course, is to celebrate their engagement at Lynley's family home. However, it looks like Lynley would have been happier to be anywhere but Howenstowe. He avoids his mother and spends most of his time sulking, especially around Lady Asherton's close friend and lover, Dr. Trenarrow.

Friends and family begin to arrive for the engagement party - among them, DS Havers and Lynley's younger brother Peter. Peter is highly resentful of Lynley, and Lynley grows concerned when he finds out that Peter has relapsed into an old drug habit.

That evening, as the Lynleys and their guests return from a play at the village hall, they find out that Mick Cambrey, the son-in-law of Howenstowe estate manager John Penellin, has been beaten to death in his shop. Suspicion falls on Penellin, who was known to dislike his son-in-law. Lynley, however, suspects that Cambrey's death is connected with a much wider web of drug smuggling. Although he is not on the case, Lynley decides to get involved to help clear Penellin's name.

But Lynley soon learns that the evidence that can clear Penellin could also condemn Peter. Will Lynley have the courage to carry out justice at his brother's expense?

!!Tropes
* AgeAppropriateAngst: {{Invoked}}. Lynley receives a WhatTheHellHero from Helen for acting like "a tortured adolescent" about his mother's infidelity to his dying father over a decade ago.
* AloofOlderBrother: Lynley has been one to Peter since he left home. He tries desperately to make up for it in this episode, now that Peter is in deep trouble.
* AssholeVictim: Mick Cambrey.
* BigFancyHouse: Howenstowe. Barbara finds herself a bit discomfited by the splendor. The way a mouse finds itself discomfited by a cat trying to eat it.
* BigNo: [[spoiler:Lady Asherton at the end when Lynley breaks the bad news to her]].
* BusmansHoliday: Lynley is not on duty and in fact is not even in ''London''. He still manages to find a case. Helen's response is to whine and complain about this. Barbara's is to immediately start bouncing case theories off him. This is important.
* ChekhovsGunman: Sidney and her annoying journalism - she snaps photographs of Cambrey's dead body in the presence of his widow and despite Lynley's telling her to stop. [[spoiler:Later, the photographs reveal a crucial detail about how the crime scene was surreptitiously altered by the murderer]].
* ClearTheirName: The reason why Lynley begins investigating is to clear John Penellin's name.
* TheConfidant: Barbara serves as this to Lynley for the first time. It won't be the last.
* ConflictingLoyalty:
** Lynley keeps begging Havers for more time before reporting that his brother Peter was the last man to see Cambrey alive.
** At the end, Lynley can't bring himself to ring DI Boscawen to report [[spoiler:Trenarrow's confession, because he knows it will break his mother's heart]].
* DysfunctionalFamily: The Lynleys. Lynley can't forgive his mother for her [[MoralEventHorizon unfaithfulness to his dying father]]. His brother can't forgive him for [[AloofOlderBrother abandoning them]]. And Lady Asherton can't reconcile the brothers.
* FirstNameBasis: {{Subverted}}. Lynley tries to persuade Havers to call him "Tommy" or "Thomas" as long as they stay at Howenstowe. Her response is a reasonably polite variant of "Oh, ''hell'' no," and she avoids addressing him directly for the rest of their stay.
* InelegantBlubbering: Lynley, at the DownerEnding.
* MistakenForServant: Havers is initially mistaken by Lady Asherton as the florist.
* MurderByMistake: [[spoiler:Peter was Brooke's intended victim, not Sasha]].
* NiceToTheWaiter: As if there weren't already enough indications that Lynley is a NiceGuy despite his BlueBlood, we see him here taking a genuine interest in the lives of his servants, including John, the estate manager, and his daughter, Nancy.
* ParentalSubstitute: Dr. Trenarrow is one to Peter.
* TheReasonYouSuckSpeech: Peter delivers one as part of his "toast" to Lynley at Lynley and Helen's engagement dinner.
* SceneryPorn: Cornwall is ''very'' pretty. The cinematographer wants you to know it.
* SelfDisposingVillain: [[spoiler:Dr. Trenarrow]].
* SheCleansUpNicely: {{Averted}}. Poor Havers looks rather uncomfortable in her evening dress.
* StylisticSuck: The performance of Oscar Wilde's ''Theatre/TheImportanceOfBeingEarnest'' at the village hall, which everyone but Lynley seems to enjoy InUniverse.
* TearfulSmile: Lynley's expression when he walks away after [[HeelRealisation accepting that he has been childish]] and asking his mother to marry Trenarrow the next time he asks. [[spoiler: A massive {{Tearjerker}} in hindsight when we realise that after all these years, Lynley's approval came too late]].
* ToBeLawfulOrGood: [[spoiler:Dr. Trenarrow]] chose to be the latter.
* VengeanceFeelsEmpty: {{Invoked}} by Lynley at the end.
--> [[spoiler:'''Dr. Trenarrow''']]: Well, you must be rather enjoying this, Tommy. [[spoiler: After all this time, my downfall]].
--> '''Lynley''': ''[quietly]'' No.
* WallSlump: Lynley does this just after insisting to Havers that he's fine.
* WhatDoesSheSeeInHim: Nancy Cambrey loves a man who not only [[spoiler:deals drugs and]] wastes their money, forcing Nancy to work long hours to make ends meet, but is also [[spoiler:a peddler of fake cancer cure, who couldn't care less about whether patients live or die]].
