There are 2 mysteries in this one book: Special Assignments and The Decorator. In this book, we mainly follow Erast Fandorin by the view of his assistant, Anisii Tulipov (Sherlock’s Watson but with his own characteristics).
*Crime was perpetrated
*Erast Fandorin was engaged as ‘special’ investigator
*Trap was laid & sprung
All in all a regular mystery book but I like the difference in culture and the settings, etc.
