The Difference Engine

Radley's toilet articles were secured in a removable envelope of water-proofed silk.

Oliphant examined the contents, handling each object in turn: a badger shaving-brush, a self-stropping safety-razor, a toothbrush, a tin of tooth-powder, a sponge-bag… He rapped the ivory handle of the brush against the foot of the bedstead. He opened the razor's leatherette case: nickel-plate gleamed against a bed of violet velour. He emptied the toothpowder out on a sheet of Grand's engraved stationery. He looked in the sponge-bag—and found a sponge.

The glitter of the razor drew his eye. Dumping its various components atop the starched bib of an evening-shirt, he used the penknife on his watch-chain to pry the fitted velour nest from the case. It came away easily, revealing a tightly folded sheet of foolscap.

Upon this sheet, in pencil, quite smudged with frequent erasure and re-erasure, was written what appeared to be the start of a draft letter. Undated, lacking any term of address, it was unsigned:

I trust you recall our two Conversations of th past Aug, during and of which you so kindly entrusted me w yr Conjectures. I am pleased to inform you that cert manipulations have yielded a version—a true vers of yr orig—which I feel most confidently can at last be run, thereby demonstrating that Proof so long sought & expected.

The remainder of the sheet was blank, with the exception of three faintly penciled rectangles, containing the Roman capitals ALG, COMP, and MOD.

ALG, COMP, and MOD had subsequently become a fabulous three-headed beast, frequent visitor to the higher fields of Oliphant's imagination. His discovery of the probable meaning of this cipher, while examining transcripts of the interrogation of William Collins, had failed to dispel the image; Alg-Comp-Mod was with him still, a serpent-necked chimera, its heads nastily human. Radley's face was there, quite dead, mouth agape, eyes blank as fog, and the cool marble features of Lady Ada Byron, aloof and impassive, framed by curls and ringlets that were proofs of a pure geometry. But the third head, sinuously swaying, evaded Oliphant's gaze. He sometimes imagined its face was Edward Mallory's, resolutely ambitious, hopelessly frank; at other times he took it to be the pretty, poisonous visage of Florence Bartlett, wreathed in fumes of vitriol.

And sometimes, particularly as now, in the rubber bath's cloying embrace, drifting toward the continent of sleep, the face was his own, its eyes filled with a dread he could not name.

The following morning, Oliphant slept in, then kept to his bed, Bligh supplying him with files from the study, strong tea, and anchovy toast. He read a Foreign Office dossier on one Wilhelm Stieber, a Prussian agent posing as an emigre newspaper editor named Schmidt. With considerably more interest, he read and a

Oliphant sighed. He very much doubted that the cha

Bligh was at the door.

"You've an appointment with Mr. Wakefield, sir, at the Central Statistics Bureau."

An hour later, Betteredge greeted him from the open door of a cab. "Good afternoon, Mr. Oliphant." Oliphant climbed in and settled himself. Pleated shades of black-proofed canvas were drawn firmly across either window, shutting out Half-Moon Street and the stark November sun. As the driver urged the cab-horse forward, Betteredge opened a case at his feet, took out a lamp, which he lit in a rapid and dextrous fashion, and fixed, with a brass apparatus of screws and bolts, to the arm of the seat. The interior of the case glittered like a miniature arsenal. He passed Oliphant a crimson file-folder.

Oliphant opened the file, which detailed the circumstances of the death of Michael Radley.

He had himself been in the smoking-room with the General and poor doomed Radley, the both of them awash with drink. Of their respective styles of drunke

Oliphant's visit had been intended deliberately to disturb Houston on the eve of his departure to France, but the display of ill-concealed mutual hostility evident between the General and his publicist had been quite unexpected.

He had hoped to sow seeds of doubt with regard to the French tour; to this end, and primarily for Radley's benefit, he had managed to imply an exaggerated degree of cooperation on the parts of the intelligence services of Britain and France. Oliphant had suggested that Houston already possessed at least one powerful enemy among the Police des Chateaux, the bodyguard and secret personal agency of the Emperor Napoleon. While the Police des Chateaux were few in number, Oliphant insinuated, they were utterly without legal or constitutional restraint; Radley, at least, in spite of his condition, had obviously taken note of the implied threat.

They had been interrupted by a page, who brought a note for Radley. As the door opened to admit the man, Oliphant had glimpsed the anxious face of a young woman. Radley had stated, as he excused himself, that it was necessary that he speak briefly with a journalistic contact.

Radley had returned to the smoking-room some ten minutes later. Oliphant then took his leave, having endured an extended and particularly florid tirade from the General, who had consumed the better part of a pint of brandy during Radley's absence.

Summoned back to Grand's by telegram in the early hours of dawn, Oliphant had immediately sought out the hotel-detective, a retired Metropolitan named McQueen, who had been called to Houston's room, number 24, by the desk clerk, Mr. Parkes.

While Parkes attempted to calm the hysterical wife of a Lancashire paving-contractor, resident in number 25 at the time of the disturbance, McQueen had tried the knob of Houston's door, discovering it to be unlocked. Snow was blowing in through the demolished window, and the air, already chilled, stank of burnt gunpowder, blood, and, as McQueen delicately put it, "the contents of the late gentleman's bowel." Spying the scarlet ruin that was Radley's corpse, all too visible in the cold light of dawn, McQueen had called to Parkes to telegraph the Metropolitans. He then used his passkey to lock the door, lit a lamp, and blocked the view from the street with the remains of one of the window-curtains.

The condition of Radley's clothing indicated that the pockets had been gone through. Sundry personal objects lay in the pool of blood and other matter surrounding the corpse: a repeating match, a cigar-case, coins of various denominations. Lamp in hand, the detective surveyed the room, discovering an ivory-handled Leacock & Hutchings pocket-pistol. The weapon's trigger was missing. Three of its five barrels had been discharged—very recently, McQueen judged. Continuing his search, he had discovered the gaudy gilded head of General Houston's stick, awash in splintered glass. Nearby lay a bloodied packet, tightly wrapped in brown paper. It proved to contain a hundred kinotrope-cards, their intricate fretting of punch-holes ruined by the passage of a pair of bullets. The bullets themselves, of soft lead and much distorted, fell into McQueen's palm as he examined the cards.
