Based on some perceptive reviews from other readers (see the links below), A Word of Six Letters seems to be a nicely representative example of Adams's work, both in quality and in theme and structure. (There are some casual mentions of golf playing here, but Adams enjoyed the sport so much that several of his books, such as The Golf House Murder (1933) and The Nineteenth Hole Mystery (1939) feature the game front and center.) The author has a penchant – and, I would argue, a talent – for weaving a thread of romance into his plotlines. The young lovers in danger here, Ella and Bruce, are likeable and practical, and the ingénu doctor serves as the nominal detective. While the author doesn't have Bruce Dickson actively searching out clues, he is nonetheless given a driving motivation to uncover the killer and keep his beloved Ella safe.
