The carriage was crowded as always, but he had managed to become pinned in a corner with his back to the wall and so when the ringtone sounded and he fumbled the phone out of his inner pocket there was nobody else who could have seen the screen. As soon as he started to watch the video message that had been sent to him, he was glad that was hemmed in right where he was with no chance of someone catching a glimpse of the footage for even a moment.
He recognised the sight of his own bedroom before he noticed anything else, but then he took note of the one thing in the room that would have looked out of place anywhere in the small apartment.
There in the middle of the floor at the foot of the bed was an eight foot wide clamshell sitting atop a small pile of rocks and dominating the room.
Before he could really take in the strange sight, the camera panned to the left and stopped at the door to the bedroom as it opened.
He recognised Jemima as she stood in the doorway and the camera zoomed in on her puzzled expression. She looked back over her shoulder and then once again at the giant clamshell as though amazed to see the thing right there before her. She never once looked down the lens of the camera or even paid it a moment of attention.
He smiled at the thought that her skills as an amateur thespian were improving.
Jemima padded into the room, her feet bare apart from the black tights that she wore under a pair of denim shorts cut off so high up that simply walking in front of the camera seemed to be part of the show. She took a sip from the straw sunk in the iced coffee that she was holding and stood a few feet from the giant clamshell, regarding it with an air of almost impish curiosity.
He smiled again at the way she studied the thing, aware of the way that she had of pulling off a layer of feigned innocence which only made her all the more attractive.
Jemima leaned forward and placed a tentative hand on the very edge of the clamshell and then jumped back, dropping the iced coffee, as the top of the shell slowly opened before her. Taking perhaps a little over half a minute to open fully, the clamshell revealed an interior that had been padded with soft, blue materials and lined with matching pillows.
Save for the upholstery, the only other item inside the clamshell was an ornate mirror that lay in its centre.
Jemima leaned forward and nervously grasped the handle of the mirror. When nothing unexpected happened, she straightened her back and examined the thing more closely. The mirror consisted of a frame made of an old, tarnished metal that might have been bronze or more likely something supposed to look like bronze. The detail of the thing was lost under the grime of years of neglect, but the silvered glass set in the metal frame was clear and intact.
Unable to resist the human urge to put such a familiar object to the purpose for which it was intended, Jemima glanced at her reflection in the mirror.
As soon as she held the mirror in front of her face, there was a sudden flash of some kind, which seemed to emanate from the surface of the glass. Jemima reacted as if stunned by the flash and staggered a little before collapsing onto the cushions and padding inside the clamshell, where she lay motionless.
Slowly as it had opened, the lid of the clamshell descended and closed, sealing Jemima inside.
The only sign of life in the bedroom was a subtle pulsing of light that escaped from within the clamshell, rising and falling like the beating of a heart.
He shook his head as the video ended and had to admit that he was impressed. He might have made the clamshell himself and engineered the mechanism that opened and closed the thing, but the mirror and the effects as well as the little display of acting were all Jemima.
Now he just had to wait, willing the train on to his destination to discover what the next act of her little play would consist of.
Jemima counted down the time she needed to remain inside the clamshell before she reached down under the padding and found the switch that opened the lid. By now the camcorder had switched itself off and she quickly made her way over to the tripod on which it stood and removed the memory card. All that she needed was a few minutes of editing on her laptop and the video was complete with special effects and ready to be sent to a certain man's mobile when the time was right. But as she was preparing things a few hours ahead of time, that could wait until later.
The first thing she attended to was checking her materials were all in place and setting the right tone for second part of the nights performance.
She started her play list of otherworldly music chosen for its similarity to the sounds of the ocean and the impressions that it conjured of underwater fantasy and drifted towards her dressing table, which had been cunningly left out of the camcorders range.
Jemima glanced over her assembled cosmetics while she slipped off her top and shorts, making sure that everything was where she had left it. As she rolled off her tights she paused for a second to run a hand over a folded garment of aquamarine colour. The fabric was a soft and smooth Lycra that reminded her of what she had planned and she quickly finished the act of undressing, spurred on by the excitement she felt at the anticipation of what lay ahead.
