The Mystery of the Quiet Lake

A new mystery for three tireless detectives!
The serene life of Olya is disrupted by the sudden visit of her ex-husband, Slava. He claims he has come for a fishing competition, but Olya suspects there is more to it than that. The news of Slava's new stunning girlfriend, the luxurious Isabella, raises even more questions for Olya.
What does such an amazing woman want from an ordinary school teacher? What is hidden in the black suitcase that Slava is so anxious about? And who is hunting for its contents, stopping at nothing?
When Slava mysteriously disappears along with the enigmatic suitcase, Olya and her loyal friends must take on the case to find the missing item — and along the way, gain something else.
