Neyo Marsh does not give up trying to establish himself in detective literature as a fighter against obscurantism. The Green Lady, the patroness of the healing spring, has just begun to siphon money from tourists, the sick, believers and... stop! Through the hands of the same poor inspector Alleyn, Marsh overthrows this cult.

But Alleyn himself is also striking. Firstly, he does not abandon his sentimental penchant for helping old maids: this time it is his own old teacher who needs the tutelage of the chief inspector. Secondly, Alleyn simply fanatically loves her job, almost like her wife. Or maybe vice versa. The policeman is devoting his second vacation to investigations and searching for killers. If such workaholism becomes a good tradition, Alleyn will simply burn out at work.

In addition to Inspector Alleyn and his teacher, the novel now and then comes across warts, asthma, and hemorrhoids. It turns out that these ailments can completely disappear with plain water without any medicine. But Marsh strongly recommends turning to ordinary doctors and not hoping for a miracle. In the current situation, the domestic Ministry of Health gladly supports her. Otherwise, it may turn out like in this book.
