Lust, Lucre, Loathing and Love

Lust, Lucre, Loathing and Love is a four-part mnemonic for motives behind murder. In Adam Dalgliesh’s investigation of Nathan Oliver’s death, it offers a compact framework for considering why someone might kill—but not a complete explanation of the motives human beings may have.

The Motive Framework

Dalgliesh recalls the formulation as a letter L capable of covering the motives for murder: lust, lucre, loathing and love. The list makes a disorderly field of human conduct seem classifiable, sorting possible causes into desire, material gain, hatred and attachment. Its usefulness is practical rather than definitive: it gives the investigator a starting point for thinking about motive, not a way to prove guilt.

Limits in the Investigation

The framework arises as Dalgliesh weighs Adrian Boyde, Jo Staveley and Jago as possible suspects. Jo’s disgust at Nathan Oliver’s cruelty, and Jago’s generosity in giving up free weekends to relieve her, suggest a shared grievance; yet none of the three seems an obvious killer. Dalgliesh recognizes that concentrating on motive at the expense of method and means would be dangerous, even as he judges motive central to this case.

The neat four-part scheme also gives way to a broader and less rational account of violence. Dalgliesh considers that motives vary extraordinarily and that some atrocious murders have no reason explicable to a rational mind. He recalls a thought he attributes uncertainly to George Orwell: “Murder, the unique crime, should arise only from strong emotions. And of course it always did.” The reflection retains the claim that murder is emotionally charged while refusing to reduce those emotions to a tidy list.
