guardsâone of them had to be sixty if he was a dayâsaluted smartly, and Colonel Armstrong returned the salutes. The guards all wore the same olive-green uniform, with a fierce-looking lion patch on the shoulder.
âAs you can see, there are two fences, with a gap of fifteen feet between them. Both fences are twelve feet high and are topped by a rather nasty array of both barbed wire and razor wire,â Colonel Armstrong said. âAlong the outer fence at intervals of four yards are electric lights capable of turning night into day at the flick of a switch.â
As the first gate closed behind us, the second began to open. The three others started into the yard, but I hesitated. Was this really wise?
Colonel Armstrong looked back. âNothing to fear, lad,â he said, and I hurried after them.
âAs we travel, we are being observed from the guard towers. Each tower is twenty-two feet high and is manned by three guards equipped with rifles. There is not a spot within the fourteen-acre compound that is not visible from one of the nine towers.â
That was reassuring, until I remembered that some of those guards were so old that they probably couldnât see very far anyway, and I didnât even want to think about how well they could shoot.
Colonel Armstrong turned around to face the guards. âArenât you gentlemen forgetting something?â he demanded.
Nobody answered.
âNo one asked us to sign in,â Colonel Armstrong said firmly.
âOh, yeah, sorry, sir,â one of the guards stammered. He opened up a wooden box and pulled out a large leather book. âIâll mark the four of you in,â he said.
The colonel started walking again, and we followed. âNew regulation Iâve instituted to keep track of visitors in and out of the compound. The guards seem to have trouble remembering. Iâm afraid itâs hard to teach old dogs new tricks.â
âI canât believe how old some of them are,â Jack said.
âItâs a reality of war that the younger men are on the front lines,â Colonel Armstrong explained.
âLike our father,â Jack said.
âExactly. I have some fine men here, though. A bit long in the tooth, but many of them were good soldiers in their time.â
âThe grounds are very well maintained,â my mother said, changing the subject. âThe flowers are just lovely!â
âYes, they are. The prisoners have established a horticultural club.â
âA what?â I asked.
âA gardening club. They also have a theatre company, book club, poetry reading group, painting classes, a bird-watching club, a newspaper, an orchestraââ
âAn orchestra?â my mother asked.
âYes. Forty-eight pieces. They mainly play the classics, but the conductor has admitted a fondness for Glenn Miller and theyâve started playing some big band and swing standards. There are also many sporting events.â
âLike soccer,â Jack said.
âWe saw them playing the other day,â I added.
âAnd just what were you two doing up here the other day?â Colonel Armstrong asked.
âI sent them to see how long it would take to walk here,â our mother explained.
âBut we hung around for a while because we were curious,â Jack confessed.
âCuriosity isnât necessarily a bad thing,â Colonel Armstrong said. âAlthough I remember something my mother always used to say: âCuriosity killed the cat.ââ
 As we continued along the path, two soldiersâtwo prisoners âcame toward us. They walked crisply, the heels of their shiny boots clicking against the concrete walkway. I felt scared. I slipped back slightly so that I was partially shielded and protected by Colonel Armstrong. I looked anxiously around for the nearest guard tower, but didnât see any guards peering out from it.
As the distance closed to a few feet, the
