Giraffe - the bane of penguins

"If you want to receive a lot of gifts on your birthday and read a mass of compliments, take care of it yourself, otherwise everyone will forget". So said Evlampia Romanova to her friend Anyuchka, who asked for help organizing a surprise for her mother-in-law's birthday, whom everyone calls Murlysa. The gift was a success: a luxurious chocolate puzzle in the shape of a palace and its inhabitants. Quickly assembling all this splendor, the women sat down for tea. Lampusha and Murlysa felt sorry to eat such beauty, but Anyuta indulged to her heart's content and… ended up in the hospital! Evlampia and Max turned to Professor Moisey Zilberkrants, a renowned specialist in toxic substances. He concluded that Anyuta was poisoned by the venom of the Cone snail found in the chocolate gift. But his colleague Yuri Derevyankin insists that Zilberkrants is mistaken. This poison comes from the lizard Gila monster. And soon Moisey Abramovich takes his own life. Why?! The vain Monya couldn't handle the shame? That's not like him. Vulf and his team begin an investigation, unaware of how many more deaths await them at the gates of the chocolate castle!
