According to Kinbote (in VN’s novel Pale Fire, 1962, Shade’s mad commentator who imagines that he is Charles the Beloved, the last self-exiled king of Zembla), superstitiously he cannot write out the odd dark word employed by his black gardener (Balthasar, Prince of Loam, as Kinbote dubbed him) with regard to Shade's murderer:
Line 998: Some neighbor's gardener
Some neighbor's! The poet had seen my gardener many times, and this vagueness I can only assign to his desire (noticeable elsewhere in his handling of names, etc.) to give a certain poetical patina, the bloom of remoteness, to familiar figures and things - although it is just possible he might have mistaken him in the broken light for a stranger working for a stranger. This gifted gardener I discovered by chance one idle spring day. when I was slowly wending my way home after a maddening and embarrassing experience at the college indoor swimming pool. He stood at the top of a green ladder attending to the sick branch of a grateful tree in one of the most famous avenues in Appalachia. His red flannel shirt lay on the grass. We conversed, a little shyly, he above, I below. I was pleasantly surprised at his being able to refer all his patients to their proper habitats. It was spring, and we were alone in that admirable colonnade of trees which visitors from England have photographed from end to end. I can enumerate here only a few kinds of those trees: Jove's stout oak and two others: the thunder-cloven from Britain, the knotty-entrailed from a Mediterranean island; a weatherfending line (now lime), a phoenix (now date palm), a pine and a cedar (Cedrus), all insular; a Venetian sycamore tree (Acer); two willows, the green, likewise from Venice, the hoar-leaved from Denmark; a midsummer elm, its barky fingers enringed with ivy; a midsummer mulberry, its shade inviting to tarry; and a clown's sad cypress from Illyria.
He had worked for two years as a male nurse in a hospital for Negroes in Maryland. He was hard up. He wanted to study landscaping, botany and French ("to read in the original Baudelaire and Dumas"). I promised him some financial assistance. He started to work at my place the very next day. He was awfully nice and pathetic, and all that, but a little too talkative and completely impotent which I found discouraging. Otherwise he was a strong strapping fellow, and I hugely enjoyed the aesthetic pleasure of watching him buoyantly struggle with earth and turf or delicately manipulate bulbs, or lay out the flagged path which may or may not be a nice surprise for my landlord, when he safely returns from England (where I hope no bloodthirsty maniacs are stalking him!). How I longed to have him (my gardener, not my landlord) wear a great big turban, and shalwars, and an ankle bracelet. I would certainly have him attired according to the old romanticist notion of a Moorish prince, had I been a northern king – or rather had I still been a king (exile becomes a bad habit). You will chide me, my modest man, for writing so much about you in this note, but I feel I must pay you this tribute. After all, you saved my life. You and I were the last people who saw John Shade alive, and you admitted afterwards to a strange premonition which made you interrupt your work as you noticed us from the shrubbery walking toward the porch where stood – (Superstitiously I cannot write out the odd dark word you employed.) (note to Line 998)
Shade's murderer, Gradus is Kinbote's double. The odd dark word that Kinbote cannot write out must be “thou” (an archaic second person pronoun used in the phrase “thou shalt not kill”). Thou Shalt not Kill is a poem by G. K. Chesterton included in Chesterton's collection The Wild Knight and Other Poems (1900):
I had grown weary of him; of his breath
And hands and features I was sick to death.
Each day I heard the same dull voice and tread;
I did not hate him: but I wished him dead.
And he must with his blank face fill my life —
Then my brain blackened; and I snatched a knife.
But ere I struck, my soul's grey deserts through
A voice cried, 'Know at least what thing you do.'
'This is a common man: knowest thou, O soul,
What this thing is? somewhere where seasons roll
There is some living thing for whom this man
Is as seven heavens girt into a span,
For some one soul you take the world away —
Now know you well your deed and purpose. Slay!'
Then I cast down the knife upon the ground
And saw that mean man for one moment crowned.
I turned and laughed: for there was no one by —
The man that I had sought to slay was I.
The poem's last line brings to mind Line 1 (identical to the unwritten Line 1000) of Shade's poem: "I was the shadow of the waxwing slain." The Shadow of the Shark is a mystery story by G. K. Chesterton from the collection The Poet and the Lunatics (1929). Among the things that Shade loathes are sharks:
Now I shall speak of evil as none has
Spoken before. I loathe such things as jazz;
The white-hosed moron torturing a black
Bull, rayed with red; abstractist bric-a-brac;
Primitivist folk-masks; progressive schools;
Music in supermarkets; swimming pools;
Brutes, bores, class-conscious Philistines, Freud, Marx,
Fake thinkers, puffed-up poets, frauds and sharks. (ll. 923-930)
Chesterton's collection of stories The Poet and the Lunatics brings to mind the two lunatics and a distinguished old poet mentioned by Kinbote at the end of his commentary:
"And you, what will you be doing with yourself, poor King, poor Kinbote?" a gentle young voice may inquire.
God will help me, I trust, to rid myself of any desire to follow the example of the other two characters in this work. I shall continue to exist. I may assume other disguises, other forms, but I shall try to exist. I may turn up yet, on another campus, as an old, happy, healthy heterosexual Russian, a writer in exile, sans fame, sans future, sans audience, sans anything but his art. I may join forces with Odon in a new motion picture: Escape from Zembla (ball in the palace, bomb in the palace square). I may pander to the simple tastes of theatrical critics and cook up a stage play, an old-fashioned melodrama with three principles: a lunatic who intends to kill an imaginary king, another lunatic who imagines himself to be that king, and a distinguished old poet who stumbles by chance into the line of fire, and perishes in the clash between the two figments. Oh, I may do many things! History permitting, I may sail back to my recovered kingdom, and with a great sob greet the gray coastline and the gleam of a roof in the rain. I may huddle and groan in a madhouse. But whatever happens, wherever the scene is laid, somebody, somewhere, will quietly set out--somebody has already set out, somebody still rather far away is buying a ticket, is boarding a bus, a ship, a plane, has landed, is walking toward a million photographers, and presently he will ring at my door--a bigger, more respectable, more competent Gradus.
