'Room Without a View' by Roger Marshall

After being missing for two years, a scientist suddenly turns up at his home, but he has been left as a vegetable after cracking-up under mental torture. When he just as suddenly disappears again, in the back of a laundry truck, Steed and Mrs. Peel follow the trail and deduce that he was abducted from London's Chessman Hotel, and has spent the years in an infamous Manchurian prison camp. Steed goes undercover as a food critic in order to meet Mr. Chessman, while Mrs. Peel takes a job as a reception clerk. But her snooping around soon gets her sent to the mysterious Room 621 and a trip to China…
