'Mornin', Mr Goldstein, sah!' Sergeant Lawrence shouted at the very top of his voice as though addressing the commander of a battalion of soldiers who was about to embark on a parade inspection.

'Goot mornink,' the bottle replied in a muffled voice. Then, without glancing at the line of men it entered the gate and waddled into the mist towards the unseen warehouse not twenty feet away.

The gatekeeper, pushing his hand between two brass buttons and into the interior of the great coat, pulled from within it a watch chain which soon enough produced a large, though not expensive-looking, watch. Glancing down at it from under his peaked cap he addressed the queue.

'I shall allow five minutes for Mr Goldstein to settle and then the first in the line will proceed through the gate to the door! You will oblige Mr Goldstein by knockin' on the outside door, whereupon you will remove your 'at and proceed in an inwardly direction and without waitin' for an answer! Mr Goldstein will be in the office to the left of the door upon which you shall again knock and then immediately enter! For them what is ambidextrous and 'asn't 'ad the misfortune to 'ave been trained in 'is Majesty's military forces, the left side is the side what's got the coat-stand!'

Anxious laughter came from the mist as men strained to catch every word, fearful of the consequences of making a mistake.

The imperious Sergeant Lawrence looked down at his watch again and then glanced sternly at Mary.

'Goldstein, you understand, miss? Mr Goldstein!'

Mary nodded, feeling herself beginning to tremble.

Mary knocked on the outer door of the warehouse and then, without waiting for a reply, did as she had been told and entered. To her left was a heavy, freestanding coat-stand on which hung the overgrown top hat together with its owner's coat and scarf. Behind it was a door with a frosted glass upper panel on which in gold relief lettering was the name Jacob Goldstein, Prop. The door seemed designed especially for Mr Goldstein, for it was not an inch higher than five feet though one and a half times as wide as one might normally expect an office door to be. Mary tapped nervously on the surface of the glass, her heart pounding in her ears, her knees feeling light, as though they might give at any moment, and the palms of her hands were wet.

'You must be here comink, please,' a voice answered in an accent which Mary immediately recognised. She had spent her childhood around Rosemary Lane and the Whitechapel markets and the accent was unmistakably that of a German Jew.

Mary entered and curtsied to the man, who sat well back from a large desk. He was dressed in a morning suit and his huge stomach, she felt certain, would not permit his very short arms to reach to the edge of the desk, the top of which contained a pot of blacking and a goose quill pen, a large writing tablet and a medium-sized brass bell of the kind a schoolmaster might use to summon his pupils from play.

'Good mornin', Mr Goldstein,' Mary said, summoning all her courage into a nervous smile.

Mr Goldstein seemed astonished to see her and commenced immediately to bluster.

'Ach! Vot is dis? A vooman? You are a vooman! Vot is vanting a vooman here? You are vanting to see me, ja?'

'I come about the job, sir. The assistant clerk… the position what was advertised?'

Mr Goldstein's bewilderment persisted and Mary added desperately, 'It were advertised on the 'oardings, sir.'

'You are a vooman and you vant you can be a clerk?' Mr Goldstein was now somewhat recovered, though still plainly bemused.

'I'm most 'appy to do a test, anythin' you want, sir! Please, your 'onour, er, Mr Goldstein, don't send me away, give me a chance, I can do it, gov… honest I can!'

Mary was suddenly conscious of Mr Goldstein staring at the region of her waist and that the merest semblance of a smile had appeared on his moon-round face.

'Abacus!' He pointed a fat finger at her midriff. 'You can use, ja?'

'Yes, sir, Mr Goldstein, your honour, since I was a brat… er child, give me a sum, any sum you like, sir.'

'In Armenia, also ven I vos a Kind! Das ist wunderbar? he chuckled. 'You are vonting I should give you some sums? Ja, I can do zis!'

Whereupon, to Mary's astonishment, he pushed his chair violently backwards. She now saw it to be on tiny wheels and possessed of a seat which could swivel. She observed that the points of his highly polished boots only just touched the floor. Using them to gain a purchase Mr Goldstein spun himself around so that the chair, with his fat dumpling body within it, flashed past her astonished face fully four times, much like an egg in an egg cup turned into a merry-go-round.

When it came to a halt Mary could see that Mr Goldstein now sat considerably closer to the ground and that his boots were planted firmly upon it. Propelling himself towards the desk his stomach now fitted neatly beneath it, the desktop coming to just under his arms.

'A test? Ja, das is gut!' He pointed to the abacus. 'From vere are you learnink zis?'

'My father, sir. 'E were in the East Hindies.'

'He is Chinee man?'

'No, sir… er, Mr Goldstein, 'e were a Dutchie, from 'Olland.'

Mr Goldstein reached for his quill and dipping it into the small pot of blacking he hastily scrawled an elaborate equation on the pad in front of him. Then he pushed it over to Mary.

Mary examined the problem scrawled on the paper tablet. Then, laying it down, she placed her abacus beside it and began immediately to move the beads across the thin wire rails, her long, slender fingers blurring with the speed of her movements. She hesitated once or twice before once again sending the bright beads flying. In a short time she slapped the last bead into place and stood back looking down at Mr Goldstein. There had never been a more important moment in Mary's life.

She looked up to see that Mr Goldstein was smiling and holding a gold hunter open in his hand. Mary announced quietly, though her heart was once again pounding furiously and she fought to keep her breathing steady, 'Eight 'undred and sixty-two pounds… at eleven pounds, fourteen shillin's and sixpence ha'penny a case, sir… er, Mr Goldstein.'

'Gut! Gut, young lady, in vun half minute! Now ve can see, ja?'

He placed the watch down on the desk and sliding open a drawer produced a large ledger which he opened and examined for a moment, running his fat index finger down several columns until it came to rest.

'Ja! Das is gut! And also schnell!'

'Beg pardon, sir?'

'Very fast!' he beamed. 'You can write also in ledger?'

He pointed to the pad on which he'd written previously and returning his quill into the blacking pot he handed it to Mary.

'Please… Numbers, also vords, let me see?'

Mr Bishop had not only provided books for Mary from the master's library but, upon her beseeching him, had on several occasions found old ledgers for her to copy out. Mary had studied these assiduously, emulating their neat columns and precise language a thousand times until she knew the contents of every page in her sleep. Now she wrote carefully in the well-formed and almost elegant copperplate she had studied so hard at the hands of her young Oxford lover, and later for countless hours on her own, to perfect.

34 cases @ a total of six hundred and twelve pounds no shillings and eightpence = seventeen pounds, one shilling and sevenpence halfpenny per case.

Then she repeated the sum in neat numerals directly below this sentence. She handed the quill and pad back to Mr Goldstein.

Mr Goldstein examined Mary's writing for a sufficient period of time for her to grow anxious that she might have made a mistake. Then he looked up, his expression stern and businesslike, shaking a fat finger with a large gold ring directly at her as in admonishment.
