The adventures of three friends continue both at sea and on land. Many years have passed since graduation from the Marine Corps, and now events are developing far from the avenues of St. Petersburg and the Finnish skerries. The tangle of military and political problems is very tangled, too many different interests are involved... And the enemy is well known, he has already opposed them more than once in different parts of the world, from Port Suez to Montevideo - a seasoned, dangerous enemy defending the interests of another Empire, over which, like over Russia, the sun never sets. Not only will the former dashing midshipmen have to deal with secret operations. They will again have to feel the trembling of the decks of warships under their feet, inhale gunpowder smoke, taking up battle in distant seas and oceans - and maybe in the thick of the jungle and on the banks of foreign rivers, because the interests of the Empire now also apply to them. And three friends, of course, will not let you down, they will cope, they will do their job - as they always did it, under any stars, at any latitudes - honestly and menacingly...
