Allmen and the Pink Diamond

Generosity, weakness for expensive pleasures and ruin is a combination that does not bode well. Johann Friedrich von Allmen was a man with a taste for women and the expensive pleasures of life. Unfortunately, his luck has run out, but now a new opportunity presents itself.

For Johann Friedrich von Allmen, boredom is not an acceptable condition. During an uninspiring reading, the art detective spontaneously steals a famous Fabergé egg from the host's possession.

Johann Friedrich von Allmen and his partner Carlos get caught up in a new adventure in which the disappearance of a very valuable koi plays a crucial role.
