Clifton is on the trail of a kidnapped Jade... back in 1912! A simple errand that turns into a car accident, and Clifton bangs his head and blacks out. An unfortunate if not uncommon occurrence, even for the dashing colonel – until he wakes up to realize that his passenger, Jade, has vanished! When, the next morning, a mysterious ‘doctor’ calls at his house to tell him a fantastical story, the skeptical Clifton is soon dragged into a very unusual investigation. Oh, and the doctor’s name? Watson. Doctor Watson. In 1972, De Groot took over the very successful Clifton series, originally created by Raymond Macherot. He began a fruitful collaboration with Rodrigue in 1999 by launching the Doggyguard series, published by Le Lombard. The latter joined him in 2002 to continue the adventures of the famous Sir Harold Wilberforce Clifton.
