Can't see the wood for the trees
The Chemistry of Death“Can't see the wood for the trees” is a phrase that comes unbidden to David Hunter as he wakes from a disturbing dream and stares toward the dark wood. Its significance eludes him in the moment, making it both a familiar saying about lost perspective and an apt figure for an investigation in which important signs are present but not yet understood.
The phrase in the dawn scene
David wakes in the kitchen, cold and confused, with the back door open and the dream still vivid. He feels that the dream carried a warning he did not want to hear, then looks toward the wood rising beyond the mist. The phrase enters his mind without an identified speaker or explanation. For an instant he senses that it means something more, but the thought slips away before he can grasp it.
The scene leaves the phrase suspended between ordinary recollection and foreboding. David has no memory of going downstairs or unlocking the door; after the phrase fades, he feels something touch the back of his neck, though the kitchen is empty and the morning still. He tries to dismiss the unease, but it persists. The narrative supplies no proof that the phrase or the sensation has a supernatural source, and its force rests instead on the uncertainty David experiences.
A pattern of overlooked evidence
The saying’s contrast between visible details and a larger pattern suits the investigation’s early failures of attention. Mackenzie tells David that no one had reported Sally Palmer missing, although she had failed to collect a grocery order and stopped visiting the newsagent for her daily paper. The village’s assumption that she had gone away or was busy writing had allowed her absence to pass largely unnoticed.
Other clues also invite competing explanations. A witness recalls that Sally Palmer was annoyed by a dead stoat left on her doorstep; Mackenzie considers whether it was a joke, a marker, or a warning, in light of the birds associated with the killer. A separate discrepancy in the evidence concerns a rough cut that leaves ridges in bone, unlike the smooth cut on a woman's vertebra. These details do not immediately yield a single answer: their meaning depends on comparison, and on resisting the temptation to treat an early explanation as settled.
Retrospective recognition
The phrase’s image of partial vision finds a concrete echo when David investigates the house where Tom Mason’s grandfather has died. David first registers the tarry smell and the resistance of the door, then sees black smears along its frame and a wad of newspaper coated in the same substance. Recognizing it as bitumen brings an earlier, faint smell from the churchyard back into focus: he realizes that Tom Mason had used the material in an attempt to seal his grandfather’s bedroom.
That recognition changes the direction of David’s suspicion. He had been convinced that Carl Brenner was the killer, but now sees that Tom Mason also fits the profile and that the material in the house connects with evidence associated with a dead woman. David tries to call Mackenzie, but there is no phone reception. He searches the house for Jenny Hammond before leaving to seek a signal, so the new deduction immediately carries both investigative urgency and personal danger.
Narrative significance
The phrase is not repeated as a solved clue, and the text does not state that David consciously applies it to any later discovery. Its significance lies in its placement: it appears at a moment when he senses meaning but cannot yet name it, while the investigation around him is accumulating signs whose relationships remain unclear. Later recognition of the bitumen shows how an apparently minor perception can become legible only when recalled alongside new evidence.
The expression therefore works as a compact image of the novel’s method of discovery. David must look beyond isolated details, but he can do so only gradually, revising his judgment as new connections emerge. The phrase’s fleeting appearance captures that interval between noticing and understanding without turning the dream into a definitive explanation.
