Nothing much. Some clues though, not to tantalise, simply to allow the vaguest word picture to appear through the mask of disguise. He is British. He has worked all his life until that came to an abrupt halt. He is almost six feet (in stout Charles Church shoes). He is straight in appearance, with a strong gait, visible cheekbones and blue eyes. His singular characteristic is determination. When the working environment is conducive, there is genuine wit in his humour.
