The story so far. Cycling historian Claude B Dawes has been summoned to meet the mysterious Dr Rudolph Moeller at M7’s underground bike testing facility in the Netherlands. M7’s top bike designer Lucyna Langelijne discovers that a very important bike part is missing

In a secure portacabin, a young guard sat patiently before an expansive bank of video monitors. He watched as images flashed before him - live feeds from the many wireless video cameras that surveyed the sprawling site.

The images went by in an endless procession:

A beer tent branded Hoegaarden
A rack of bikes
A row of EasiFlush portable toilets
A rack of bikes
A first aid tent
Another rack of bikes

As the pictures went by the guard fought off a day-dream. Suddenly an image before him registered alarm. With a reflexive jerk his hand shot out and hit the freeze button on the control panel. The reading on the monitor told him that it came from camera 43. It should have been overlooking one of the smaller bike parking areas.

But the image before him was not of rackfuls of 3 speed Gazelles.

He called his supervisor. The screen showed a small red blinking device with two wires linked to what seemed like a bike wheel and sections of bike frame. On adjusting the contrast the words “Cat Eye” could just be discerned. On the cylindrical surface of the hub the M7 logo could also be seen. What was the signifigance the flashing red light? And where had the camera been taken to transmit the image?
