If you have given all the necessary orders, Ramage told himself, it is time you started thinking about what this damned French frigate's appearance means. Well, it means your original idea of sheltering in the lee of Giglio until the scirocco blows itself out, and then going over to Port' Ercole, has gone by the board.

So now you have to keep out of this wretched frigate's way for the next two or three days, so that the garrison commander on Giglio does not realize he was hoodwinked. Also it is vital that no alarm is raised by the French on the mainland so that extra guards will be watching the second group of hostages.

But just consider being chased for three days by this frigate, which is identical with the Calypso, and therefore of the same strength in terms of guns and, since there is no reason to suppose otherwise, as fast and weatherly . . .

So the Calypso has first to be a plover, protecting her chicks or the eggs she is hatching in the shallow depression on the ground that passes for her nest. On the approach of an enemy, be it stoat, fox or human, the plover runs away, one wing dragging as though she is hurt, trying to lure the threat away from the nest. Her shrill cries of distress and injured appearance usually work.

Could the Calypso be as effective as a plover? The more he thought about it, the more certain he was that she could not: by the time the scirocco blew itself out, the two frigates would have had to fight each other, and one would have been destroyed or captured.

Very well, he must make sure it was not the Calypso, and if the French were not to raise the alarm, then the fight had to take place out of sight of lookouts on the mainland. Or at least the French on shore must not be able to connect the sea fight with the Port' Ercole hostages.

Come to think of it, as long as the Giglio commandant did not connect the frigate with his former hostages, there was nothing to fear. More important, there was no reason why the commandant should, so long as that frigate to the south did not open fire on the Calypso while still in sight of Castello.

At that moment Ramage saw General Cargill coming up the quarterdeck ladder, buckling on a sword. "What's all the commotion about, eh?" he demanded.

Ramage shrugged and pointed at the small grey shadow now astern. "A French frigate."

"Ha, and how are you going to engage her, eh?"

"We're not," Ramage said calmly. "We're trying to avoid her - it will be dark in an hour."

"Avoid her! You mean you're running away?" Cargill shouted, banging the hilt of his sword. "Why, that's cowardice!"

Ramage walked to within a foot of the man, not wanting everyone to hear the conversation. "You will answer for that remark later," he said coldly. "In the meantime I must ask you to leave the quarterdeck."

"I'll be damned if I will!" Cargill exclaimed. "If there's going to be fighting, my post is here."

"You've already decided there's not going to be any fighting, and I must remind you that I am in command of this ship. If you do not go below I shall place you under an arrest and two Marines will take you below."

Cargill, eyes shifty, suddenly realized that he had just called Ramage a coward on his own quarterdeck and that Ramage had challenged him to a duel. Perhaps he had been a little hasty, Cargill admitted to himself, but dammit the fellow was running away. And anyway, who was he to threaten to arrest a field officer? A pipsqueak of a captain threatening to arrest a general!

He felt a tap on the shoulder and whirled to find Sir Henry standing there; it was obvious the admiral had heard the entire conversation.

"General Cargill, I suggest you go down to your cabin."

"But this fellow Ramage is -"

"Go down to your cabin and wait for Captain Ramage's seconds to call on your seconds," Sir Henry said. "No gentleman can be called a coward without demanding satisfaction. And, if I might express a personal opinion, no gentleman would call the captain of one of the King's ships a coward on his own quarterdeck unless that person fully understood what was happening."

"But Sir Henry, I can see with my own eyes what's afoot!" Cargill protested.

"In that case," Sir Henry said quietly, "I should tell you that Captain Ramage has every right to arrest you if you refuse to obey his orders. Me, too, if I did the same."

Cargill swung round, staggering as the Calypso rolled, and then made his way to the ladder. Sir Henry, without a word to Ramage, returned to the taffrail.

Ramage sighed: if one had to fight only the French ... He took the telescope from the binnacle drawer and balanced himself to inspect the French frigate. Yes, she was following precisely in the Calypso's wake. Her guns were not run out - but because she was not suspicious or because she was rolling so violently? Topsails and courses set, the same as the Calypso. If there was an urgent need to overtake the Calypso, surely she would let fall her topgallants? Ramage looked aloft at the Calypso's straining topsails and then decided only a gambler would set topgallants: a sudden extra gust in this uncertain weather could easily carry away a mast. . .

So what was that French captain doing and thinking? At first, no doubt, interested (and surprised) to see a ship of his own class off Giglio and obviously weighing anchor. A sensible captain would conclude that the ship was being prudent, shifting berth in the scirocco to the lee side of the island. So far so good.

Then the ship bears away and sets more sail without apparently answering the challenge. How important would the Frenchman judge that? His reaction would not be as rigid as a British post-captain, for at least four reasons. First, there were so few British ships in the Mediterranean that the Frenchman would not be expecting to see one - certainly not at anchor off Giglio.

Second, the French captain would notice at once that the ship was the same class as his own, and it was unlikely anyone would see in this wind that the sails had a British cut. Third, the captain of a French frigate in the Mediterranean was unlikely to have heard (or would have since forgotten) that a French frigate of this type had been captured by the British some years ago in the West Indies.

Fourth, the French were very casual about signalling, and this captain might not - since he would assume that any other ship would be French - be very concerned that his challenge was not answered.

However, Ramage decided, any French captain might be curious if the frigate he was following stayed on this course, which led to nowhere in particular. North-east could only mean somewhere on the Tuscan coast, fishing villages between Castiglione della Pescaia and Talamone . . . Turning to the northwest, though, would show clearly that the destination was Elba, which in turn meant Porto Ferraio. And of course Porto Ferraio, one of the safest harbours in the whole Mediterranean, was on the north side of Elba and well sheltered in a scirocco.

Ramage acknowledged Aitken's report that the Calypso was now at general quarters and nodded in agreement when the first lieutenant said he presumed Ramage did not want the guns run out yet. Ramage noted that Southwick had now joined Aitken. It was a deuced nuisance that Sir Henry had installed himself at the taffrail: Ramage wanted to pace the weather side between the quarterdeck rail and the taffrail, but if he did that now it would be obvious (and unnecessarily rude) to Sir Henry that he was avoiding conversation.

It was curious about plovers. In Kent they were called peewits, which was a fair approximation of their cry. But how did they learn that trick of shamming injury to a wing to lure intruders away from the nest? Or did it come to them naturally, like swimming to ducklings and baby moorhens? Hmm, night was falling fast: darkness was getting a helping hand from the haze, which was almost thick enough to log as a faint mist.
