The second case of Commissar Brennon and consultant Longsdale.
After a strong fire, a charred skeleton was found in the church of St. Helena. The consultant is sure that the matter is unclean - in every sense, and the commissar must establish what happened to the deceased.
However, while Brennon and Longsdale are busy investigating, the mysterious Mr. Redfern intervenes in the case, whom Margaret Sheridan, the Commissar's niece, met.
Continued every Monday.
