Years have passed since the end of the war, but they are still full of strength and faithful to each other. Now they have different professions, different positions in society, but they are still together, former heroes of the Resistance, and now fighters against injustice. Those who are known only by their call signs: Elephant, Leopard, Tiger, Wolf and of course the group leader, Fox. And now they sometimes have to take the path of fighting murderers, thieves, drug dealers and other evil spirits again - after all, they are the “Zoo Gang” and they are not indifferent to what is going on around them.

The series of detective stories was written by Paul Gellico in 1971, translated into Russian and published in the anthology of foreign detective stories “Avers” in 1991.
