The setting is interesting (a six-day walk-and-run marathon contest in mid-Victorian London), as are the characters. The writing is full of period color, too. And if those were the only factors, I'd rate this book five stars. But in "Wobble to Death," as in another Sergeant Cribb mystery, "The Detective Wore Silk Drawers," the solution to the crime is almost a throwaway, hastily given and not altogether convincing. It is as though an editor told the writer that he had already written 200 pages and that the book had to end in five more, regardless. The finales of both "Wobble" and "Silk Drawers" were so disappointing that they soured the enjoyment that had carried me through both books. That's a shame, because otherwise they are quite entertaining.
