Mopping his brow, the nervous one pushed home the vault door, spun the locking wheels, dialled the combination, and set the clock for the time-lock. The Amsterdam Exchange vaults would now remain shut, sound-proof and air-tight, until nine o’clock on the following Monday morning.
No human agency except a massive bomb could open the door from the outside.
And no way had yet been devised for performing the operation from the inside.
The stillness within the vault was almost palpable, the air heavy and hot. No sound came, and no living thing stirred.
So the shattering noise as the end panel of one of the crates was violently kicked out, seemed all the more horrendous because of the oppressive silence.
Feet first, a dark figure wriggled into the total blackness of the vault. Despite the increasing warmth (which would eventually come under thermostatic control at 70 degrees Fahrenheit), the intruder shivered, for the place had about it the feel of the tomb.
The beam of a slim torch cut through the Stygian darkness, and illuminated the other crate. With tools from the air-conditioned ‘living space’ in the first box, the burglar levered off the end panel of the second, and drew out more tools, plus battery lights, portable breathing apparatus, a radio, and a plentiful and varied supply of food and drink.
A battery light came on, and the dark form of the thief was revealed, clad from head to foot in the sinister all-black garb and hood of a Ninja Assassin.
Periodically, the hood was lifted to enable the intruder to breathe through a mask attached to an oxygen tank.
Finally, Sabrina Carver pulled the hood off altogether, and released her flowing hair. She switched on the radio, and settled down to a packet of smoked salmon sandwiches and a bottle of excellent Pouilly Fuissé.
It was going to be a long wait until Monday morning, she thought, with only the theft of a small fortune in diamonds to while away the time.
The electric clock controlling the time-lock jumped from two minutes of nine to one minute. The security manager started in sympathy, despite the fact that his Monday morning routine of opening the vaults had not varied since he joined the staff of the Amsterdam Diamond Exchange twelve years before.
The machinery had merely got more sophisticated, and though the clock made no noise as it ticked off the minutes, the security manager, being nervous, acted as if the passage of the long hand was the crack of doom.
He was accompanied by the Deputy Director of the Exchange — again, as normal — and lurking discreetly behind them were two armed and uniformed guards. One kept a wary eye on van der Goes’s fussy little agent.
Nine o’clock.
A white bulb over a switch box next to the vault door blinked on. A plaque in the wall identified the box as the ‘Time Vault Release’. A security guard reached out a long arm and, on the nod of the Deputy Director, pressed down a lever.
The security manager breathed a sigh of heartfelt relief, and stepped forward to turn the large combination dial, and spin the wheels in reverse direction.
The guards lifted their weapons and flanked the two executives.
With a solid metallic ‘clunk’, the bolts inside the vault slid along their tracks, and the mighty door swung soundlessly out.
The security manager looked over his shoulder at his boss, smiling for the first time during the entire weekend.
The five men outside the vault barely had time to register the unbelievable scene … steel deposit boxes lying open, some scattered on the floor, clearly empty, alongside a trio of equally empty wine bottles.
Then the bizarre black hooded figure was on them.
The guards did little more than gape, because the intruder was clear past before they realized there had been anyone in the vault at all.
They were left with one scarcely possible, lunatic impression: of the sound of whirring wheels.
It was only when the hooded figure had gone that one guard turned on his heel, loosed off a departing shot, and shouted, ‘Roller skates! It had roller skates!’
In the outer lobby, secretaries and early arriving businessmen dived for safety as the apparition sped across the marble floor in long, crouching strides. Sabrina saw the far wall looming up, and made a dramatic power leg-over-leg turn.
The racing wheels of the skates fixed to her boots screeched jarringly on the marble as she clipped a corner and shot into a corridor.
The few girl clerks, more soigné secretaries, and portly office managers in her way, scattered in horror and flattened themselves against walls or ducked into open doors to give her a clear passage.
Accelerating all the time, she pumped powerfully and unstoppably down the corridor, and from there to another, hunched forward in racing style, her arms swinging in surging rhythm, her eyes pools of brightness in the dark hood, a black knapsack clipped to her back.
Through a third corridor she rushed and a fourth, navigating a half-open glass door, and with more hair-raising right-angled turns, until she knew she was once more at the rear of the building.
It was an exhibition of breathtaking skill, streaking through knots of terrified people, skimming obstacles, trolleys, file-toting clerks, all the while gaining power and acceleration.
And finally, she was in a cul-de-sac.
She looked steadily ahead, gritting her teeth, bunching her muscles.
The passage ended not in a wall but in a floor-to-ceiling picture window. Sabrina careered towards it, went into an even lower crouch, let loose a yell of exultation, and sprang into the air.
She launched herself at the glass, booted feet and gloved fists leading, and pulped it to smithereens, bursting through into the cool air in a shower of splintered fragments.
Arms wheeling like a ski-jumper, she cleared the sidewalk and a disbelieving pedestrian. She landed fully-balanced in the roadway and, without stopping, leaned into a turn and roared away down the slight gradient.
An areaway, no more than an alley, came up on her right, just where it should have been, just the way she had planned it.
She sped into it, dodging garbage bins, and reached a sheltered open space at the back of an off-centre theatre.
Behind her she heard the wailing of klaxons, and the shouts of guards and police who were belatedly on her track. Sabrina spun to a stop, and slipped off her skates, stowing them in the unclipped haversack. With a key from her belt she let herself into the almost deserted theatre.
The people goggling at the unaccustomed activity in the quiet street, took the dazzlingly lovely girl in the pant suit for an actress, even if only because she had exited from a theatre. She had a large tote-bag slung over her shoulder, and she smiled winningly at the guards tearing past her.
Once in the Weesperplein, Sabrina caught a tram to the Rijksmuseum, spent half an hour there soaking up the Rembrandts, and walked through the pedestrian precinct to the Grand Hotel Krasnapolsky in Dam Square.
At the Amsterdam Diamond Exchange, the Deputy Director and the security manager were comparing notes with the police.
‘I make it probably four hundred thousand dollars’ worth in the unlocked boxes,’ the Deputy Director said, ruefully. ‘Thank God it was a slack weekend, and there wasn’t more there.’
‘It was enough,’ the security manager intoned. ‘My, oh my, it was enough.’ He breathed out noisily, and shook his head in tragi-comic weariness. ‘Roller skates. I ask you — roller skates.’
‘What about my client’s gold?’ demanded the agent of Kees van der Goes.
