Here is a set of swashbuckling, breathtaking adventures among the stars, in the future yet to come. Sir Dominic Flandry, captain in Earth’s Imperial Naval Intelligence Corps, schemes and fights his way through a clutch of enemies, human and nonhuman.

At the same time, these stories deal with more than wild battles, hairbreadth escapes, and escapades involving some of the galaxy’s most enticing young ladies. Beneath all the swashbuckling there is a view of history, as it has been and as it perhaps always will be.

The wildest adventures seem to come at two different stages in the life of a civilization. First the adventures come when the civilization is fresh, vigorous, and aggressively expanding. But there is also the time when the civilization is old, when it wants nothing but to be left in peace. Then the ruthless new peoples arise, beyond the imperial borders or even within them. It happened to Egypt , Persia , India , China , Greece , Rome . Someday it may happen to all Earth.

In those eras, someone must man the ramparts. He may be a Roman legionnaire, or he may be an intelligence agent of Terra’s empire among the stars. But he is always a lonely man. Sir Dominic, no grim and humorless professional hero, can crack a joke, hoist a bottle, or kiss a girl with the best of them. But he sees the barbarians pressing inward through the stellar marches. He sees the purpose of the powerful, nonhuman Merseian Empire — to end the uneasy peace with mankind by sweeping mankind aside. And he sees corruption and cowardice at home. If the Long Night is not to come in his own lifetime, if the things he cares about are to be saved, he must do what he can.

And he does it very well — often lethally well. When a gang of atomic-powered savages are unwise enough to kidnap him, they find they have a tiger by the tail. When a traitor begins to intrigue with the enemy, that creature finds himself up against an agent who can out-intrigue him in cards and spades. From world to world Flandry goes, risking his neck time after time, that Earth may live.

Captain Flandry opened his eyes and saw a metal ceiling. Simultaneously, he grew aware of the thrum and quiver which meant he was aboard a spaceship running on ultradrive.

He sat up with a violence that sent the dregs of alcohol swirling through his head. He’d gone to sleep in a room somewhere in the stews of Catawrayannis, with no prospect or intention of leaving the city for an indefinite time — let alone the planet! Now—

The chilling realization came that he was not aboard a human ship. Humanoid, yes, from the size and design of things, but no vessel ever built within the borders of the Empire, and no foreign make that he knew of.

Even from looking at this one small cabin, he could tell. There were bunks, into one of which he had fitted pretty well, but the sheets and blankets weren’t of plastic weave. They seemed — he looked more closely — the sheets seemed to be of some vegetable fiber, the blankets of long bluish-gray hair. There were a couple of chairs and a table in the middle of the room, wooden, and they must have seen better days for they were elaborately handcarved in an intricate interwoven design new to Flandry — and planetary art-forms were a hobby of his. The way and manner in which the metal plating had been laid was another indication, and—

He sat down again, buried his whirling head in his hands, and tried to think. There was a thumping in his head and a vile taste in his mouth which liquor didn’t ordinarily leave — at least not the stuff he’d been drinking — and now that he remembered, he’d gotten sleepy much earlier than one would have expected when the girl was so good-looking — Drugged — oh, no! Tell me I’m not as stupid as a stereofilm hero! Anything but that!

But who’d have thought it, who’d have looked for it? Certainly the people and beings on whom he’d been trying to get a lead would never try such a stunt. Besides, none of them had been around, he was sure of it. He’d simply been out building part of the elaborate structure of demimonde acquaintances and information which would eventually, by exceedingly indirect routes, lead him to those he was seeking. He’d simply been out having a good time — quite a good time, in fact — and—

And now someone from outside the Empire had him. And now what?

He got up, a little unsteadily, and looked around for his clothes. No sign of them. And he’d paid three hundred credits for that outfit, too. He stamped savagely over to the door. It didn’t have a photocell attachment; he jerked it open and found himself looking down the muzzle of a blaster.

It was of different design from any he knew, but it was quite unmistakable. Captain Flandry sighed, relaxed his taut muscles, and looked more closely at the guard who held it.

He was humanoid to a high degree, perhaps somewhat stockier than Terrestrial average — and come to think of it, the artificial gravity was a little higher than one gee — and with very white skin, long tawny hair and beard, and oblique violet eyes. His ears were pointed and two small horns grew above his heavy eyebrow ridges, but otherwise he was manlike enough. With civilized clothes and a hooded cloak he could easily pass himself off for human.

Not in the getup he wore, of course, which consisted of a kilt and tunic, shining beryllium-copper cuirass and helmet, buskins over bare legs, and a murderous-looking dirk. As well as a couple of scalps hanging at his belt.

He gestured the prisoner back, and blew a long hollow blast on a horn slung at his side. The wild echoes chased each other down the long corridor, hooting and howling with a primitive clamor that tingled faintly along Captain Flandry’s spine.

He thought slowly, while he waited: No intercom, apparently not even speaking tubes laid the whole length of the ship. And household articles of wood and animal and vegetable fibres, and that archaic costume there — They were barbarians, all right. But no tribe that he knew about.

That wasn’t too surprising, since the Terrestrial Empire and the half-dozen other civilized states in the known Galaxy ruled over several thousands of intelligent races and had some contact with nobody knew how many thousands more. Many of the others were, of course, still planet-bound, but quite a few tribes along the Imperial borders had mastered a lot of human technology without changing their fundamental outlook on things. Which is what comes of hiring barbarian mercenaries.

The peripheral tribes were still raiders, menaces to the border planets and merely nuisances to the Empire as a whole. Periodically they were bought off, or played off against each other — or the Empire might even send a punitive expedition out. But if one day a strong barbarian race under a strong leader should form a reliable coalition — then vae victis!

A party of Flandry’s captors, apparently officers, guardsmen, and a few slaves, came down the corridor. Their leader was tall and powerfully built, with a cold arrogance in his pale-blue eyes that did not hide a calculating intelligence. There was a golden coronet on his head, and the robes that swirled around his big body were rainbow-gorgeous. Flandry recognized some items as having been manufactured within the Empire. Looted, probably.

They came to a halt before him and the leader looked him up and down with a deliberately insulting gaze. To be thus surveyed in the nude could have been badly disconcerting, but Flandry was immune to embarrassment and his answering stare was bland.
