Hasamba

A group of girls and boys set up a secret society called "Hasamba"; their adventures take place, first during the British Mandate and the struggle for statehood of Israel, and then as they battle their country's enemies: infiltrators, spies, criminals and other offenders.

This includes the Electric cave, an intelligent robot, "Zagloba," that helps the group in some adventures, a laser rifle, and more (Yigal Mossinson himself was the inventor of patents).

The main character, the handsome leader Yaron Zahavi, was inspired by Yaron London, now a well known Israeli journalist, and the son of a famous Israeli actor, and the other characters, like "Tamar", "Fat Ehud", "Skinny Uzi", or "Menashe the Yemeni" and others, were created based on the children of Kibbutz Na'an (and to whom the books were dedicated: "To the children of Na'an, the yellow (blond), the black, and the red-headed"), where the author, Yigal Mossinson, lived from 1938 to 1950.

Also the enemies are people with names and characters, like the antisemitic British police detective sergeant Jack Smith aka the "Red beetle", the dangerous thief Elimelech Zurkin, and the ruthless mercenary-saboteur Nazi Von-Bilov.

The series, by Yigal Mossinson, was first published in 1950 and was extremely popular (over a million copies sold in Israel;[2] "national acclaim"[1]), and a model for many children at that time for courage and conduct.
