At long last the BBC Holby City website has added a character page for Luc Hemingway, along with this photo.

Unconventional and supremely intelligent, this wanderlust-filled traveller has settled at Holby for now. A fiercely curious personality, Luc revels in medical minutiae and can spot diagnoses others might miss. His scant regard for hierarchy or politicking means he is more comfortable with those on the fringes of society. Luc’s ironic humour and Zen-like approach is often endearing although he rarely lets people get close.
