Four short lines, and someone has already been talked into something. The title, "Collaborator," does much of the work because the word pulls two ways. In everyday use a collaborator is a partner, someone who helps make a thing. In the harsher vocabulary of occupation and conflict, it is a person who cooperates with a power they ought to resist. The poem never settles on one meaning, and its tension lives in the gap between them.
The first line begins in lowercase, mid-thought: "where night is about." It reads like the tail end of a sentence we missed, as if we have walked in on something already under way. The grammar is slippery, too. "Night is about" can mean night is abroad, astir, nearby, the way we say there is a thief about. But "about" also means "concerning," so a second reading sits underneath the first: a place where night is the subject, the theme. Either way, night is no neutral backdrop. It is an active presence that makes demands.
The speaker's reply is "I must supply my inch." Each word is chosen with care. "Supply" is a quiet, businesslike verb, the language of orders filled and provisions handed over, and it makes surrender sound like helpfulness. "Must" admits there is no real choice. And "my inch" is a wonderfully small unit with a possessive attached. The speaker is trying to hold a boundary: this much, and no more. Behind the phrase stands the old saying about giving an inch and having a mile taken. The poem never quotes it, but the second stanza acts it out.
After the stanza break comes the consequence: "and promise much / against my will." The little conjunction "and" shows how easily one thing leads to another. The inch does not stay an inch. "Inch" and "much" even chime across the gap. They are not a true rhyme, since the vowels differ, but they share a closing consonant sound, so the smallest measure and the largest quantity are tied together by sound. A promise also reaches forward in time, binding the speaker to what has not happened yet. The final word, "will," means volition, but it is also the word that marks the future tense, and one can hear both: the speaker's will is overridden, and the promises still to be kept are already waiting in the language.
The sound of the poem supports this reading. There is no punctuation at all, so the stanza break stands in for a full stop. The lines run 5, 6, 4 and 4 syllables, getting shorter and tighter as they go. The rhythm grows more orderly as the speaker gives way. Line two is a clean iambic trimeter, "I MUST supPLY my INCH," each beat landing exactly where it should, as if the verse itself were obeying. The last line, "aGAINST my WILL," is a compact two-beat phrase that ends on a heavy stressed monosyllable, like a door closing. The protest comes last, but it comes after the concession and changes nothing.
The title invites one more reading, which concerns the poem's own making. If the speaker is a writer working in the dark, then "my inch" might be the few words a poem asks for, and the poem then promises more than its maker meant to say. Collaboration with night would then be a creative partnership in which the poet is the junior partner, supplying a little and being carried much further. The text does not insist on this, but it allows it, and the allowance is part of its richness.
What makes the poem worth reading is how much it holds in fifteen words. It describes how complicity begins: not with a grand betrayal but with a small, reasonable-sounding concession, and then a promise that outgrows it. It leaves out names, places, and causes, so the situation can be political, personal, or artistic, and the reader brings whichever dark they know. The poem's own discomfort is also instructive. The speaker is neither villain nor hero, only someone who has noticed too late how far an inch can go.
