Death appears in the first line of Dave Bonta's poem, and nothing dramatic happens. He carries no scythe and summons no one. He is simply "walking / up and down", the way a person paces a platform waiting for a train, and he has company: a watchmaker. That odd pairing drives the whole poem. Who better to walk beside Death than someone who spends his days dividing time into tiny, exact pieces? Yet the watchmaker talks about neither clocks nor mortality. He talks about a river.
The river is named only in the title. The Fleet is a real stream, one of London's lost rivers, long ago built over and sent underground. The poem never explains this, and it doesn't need to. What matters is the speaker's distance from the thing described: a river "I had never seen." He knows it only because someone "told me." That small phrase sets up a chain of hearsay, and it quietly links the river to Death. Both are things we mostly know by report. Here, though, one of them is pacing right beside the storyteller, which gives the scene an unsettling calm.
The form is as plain as the subject. Eight short lines, most of them only three to five syllables, make up a single sentence with no rhyme and no commas, just one full stop at the very end. That unbroken syntax works like the river it describes: the sentence runs through its narrow lines the way water runs through a channel. The line breaks do real work as well. "Was at home in" ends on a small preposition, so the reader hangs for a beat before the poem arrives at its destination. That destination, "a great and dirty pipe", is the longest line, at six syllables, and it ends on the blunt, hard word "pipe".
Sound ties the poem together quietly. The soft w's of "walking," "with," "watchmaker," "who" and "was" give it a murmuring undertone, as if the lines were being told in a low voice. "Death" and "dirty" sit at opposite ends of the poem with the same hard d, so the last line seems to echo the first. And the two phrases built on "and", "up and down" and "great and dirty", mirror each other. The first suggests restless, aimless movement. The second brings opposites together in one image.
That last phrase is the most interesting in the poem. "Great" can mean enormous, but it can also mean grand or admirable, and "dirty" cancels or complicates that grandeur at once. Then there is "at home," a cosy, domestic idiom that sits oddly beside the word "pipe." The poem does not pity the river or protest on its behalf. It reports, deadpan, that the river has adapted. Death gets the same treatment: he strolls rather than looms. The poem takes the two biggest things in it, time and death, and gives them the casual tone of a conversation overheard.
Judging by these images, the buried river can be read as a picture of how we live with mortality. Something wild and natural keeps flowing in a channel humans have built, out of sight and not entirely comfortable, but somehow settled. The watchmaker, keeper of time, is the one who understands this. Perhaps time too goes on running whether or not anyone sees it, and Death's pacing is part of its steady current.
The poem's significance lies in what it leaves unsaid. It offers an anecdote, an odd companion and a hidden river, and trusts the reader to feel the connections. It makes the uncanny ordinary without making it any less strange. After a few seconds of reading, you are left with an image of something enormous and unseen going on beneath the streets, and with the faint comfort that it is, in its own way, at home.
