Black cuckoo

No one knows where this black bird, similar to a cuckoo, flies to Ella Richenko's yard. And a woman who leaves her children is called a "cuckoo". Is it really so? A mother's love is the greatest thing in the world. From love the world was born, love keeps people and animals close to each other, even when it seems that there is no more hope. It is very bad when a mother has no love for children, this happens... But, trouble, when there is too much of it.... and then, she is terrible with her all-encompassing passion, which burns in her path everything that does not meet her criteria. Beware of great love!" — ponders the old cleaner, a former investigator who helped Rykov discover the killer with her advice.
