Roger had been working at a military research facility ever since his university studies were complete. The focus of his work was nanorobos – sub cellular sized robots designed to repair human tissue. After ten years in this work he had had enough and left, taking some of the fruits of his labours. The hardware for producing the robos was about the size of a briefcase and the software could run on a standard dedicated PC.

Over time it had not been difficult for him to arrange for an extra unit to be made and lost. He had also developed mechanical mosquitoes for the introduction of robos into unsuspecting subjects for espionage purpose. The robos were so small that several thousand could be injected in one mosquito bite. He also managed to get a few of these for his own use.

The software was quite sophisticated; once the camera had determined the part of the body where the mosquito had injected the robos they could navigate to any part of the body through the bloodstream. Once in place, the robos could actually go into cells and cause them to replicate. Thus they could grow new tissues and make physical changes to the body. They could also stimulate nerve cells both in the body and in the brain.

The tricky bit was getting the mosquito to the subject. Once the robos were in it was simple. They could be preprogrammed or controlled by radio waves remotely. The subject had to be in view of the camera until the mosquito landed. The camera could be concealed in a briefcase and had a very wide-angle lens so it only had to point more or less in the direction of the subject...
