Rhona MacLeod 03-Deadly Code

Spike is not your normal teenage runaway. He is being pursued by both MOD and the FBI not to mention the shadowy group ReAlba. All of them want Spike alive. The question is why? 
The left foot had been severed from the leg ten centimetres below the patella. Both fibula and tibia bones were divided at the same place. All the toes were intact, although the nails had disintegrated or been eaten off during the foot's time in the water.
Dr Rhona Macleod travels north to investigate a grisly discovery - a severed foot, caught in a fishing net off the Isle of Skye. Where is the rest of the body, and who is the dead man? What links him to a sinister secret society in America? And why is the Ministry of Defence so keen to shut down the case? 
Rhona's investigations embroil her in an international conspiracy from which she will be lucky to escape unharmed..
