Again and again with incredible speed the bowman sent his missiles hissing through my ignition point。 It required all my concentration to maintain the necessary stream of energy； moving it occasionally as his point of aim changed。
Finally； he dropped his bow back to his side。
〃That oughta do it； youngster；〃 he grinned。 〃Take a look。〃
I did。 There in the distance； behind the soldiers' lines； thin plumes of smoke were rising from the wagons。 In a few moments； Claude's supply pany would be without supplies。
If we had a few moments！ As we watched； the men began to advance on Aahz and Gus； their swords gleaming in the sun。
〃Think we'd better do something about that！〃 Ajax muttered； raising his bow again。
〃Wait a second； Ajax！〃 I ordered； squinting at the distant figures。
There had been a brief consultation between Aahz and Gus； then the gargoyle stepped back and began gesturing wildly at his panion。
It took me a moment； but I finally got the message。 With a smile； I closed my eyes and removed Aahz's disguise。
Pandemonium reigned。 The soldiers in the front ranks took one look at the demon opposing them and stampeded for the rear； half trampling the men behind them。 As word spread through the formation； it became a rout； though I seriously doubt those in the rear knew what they were running from。
If anyone noticed the burning wagons； they didn't slow once。
〃Whooee！〃 Ajax exclaimed； thumping me on the back。 〃That did it。 Look at 'em run。 You'd think those fellers never seed a Pervert before。〃
〃They probably haven't；〃 I mented； trying to massage some feeling back into my shoulder。
〃You know；〃 the bowman drawled； squinting at the scene below； 〃I got me an idea。 Them fellers ran off so fast they fergot to signal to anybody。 Think we should do it for 'em？〃
〃How？〃 I asked。
〃Well；〃 he grinned。 〃I know the signals； and you're a magician。 If I told you what signal to run up； could you do it？ Without anybody holdin' it？〃
〃Sure could；〃 I agreed。 〃What'll we need for the signal？〃
〃Lemme think；〃 he frowned。 〃We'll have to get a skull； and a couple of pieces of red cloth； and a black ball； an…〃
〃Wait a minute； Ajax；〃 I said； holding up a hand。 〃I think there's an easier signal they'll understand。 Watch this。〃
I sent one more blast of energy out； and the tower platform burst into flames。
〃Think they'll get the message？〃 I smiled。
Ajax stared at the burning tower for a moment。
〃Yer pretty good at that； youngster；〃 he murmured finally。 〃Throwin' fire that far。〃
〃Well；〃 I began modestly； 〃we magicians can…〃
〃 'Course；〃 he continued。 〃If you can do that； then you didn't really need me and Blackie to handle those wagons； did you？〃
Too late I realized my mistake。
〃Ajax； I…〃
〃Kinda strange； you goin' to all that trouble jes' to convince me I'm not useless。〃
〃You're not useless；〃 I barked。 〃Just because sometimes you're not necessary doesn't mean you're useless。 I may be young； but I'm old enough to know that。〃
Ajax regarded me for a moment； then he suddenly smiled。
〃Danged if you aren't right； youngster 。 。 。 Skeeve；〃 he laughed。 〃Guess I knew it； but plum fergot it there fer a while。 Let's go get some wine from that cask strapped to your dragon。 I'd like to thank you proper fer remindin' me。〃
We headed back to camp together。
Chapter Twenty
〃Chain of mand is the backbone of military structure and must be strictly obeyed。〃
…F。 CHRISTIAN
The mood back at the camp was understandably celebratory。 If I had had any hopes for joining in the festivities； however； they were dashed when Aahz hailed me。
〃Over here； kid！〃 he waved。 〃We've got some planning to do！〃
〃That's the other side o' bein' a general； youngster；〃 Ajax murmured sympathetically。 〃 'T'aint all speeches and glory。 You go on ahead。 I'll do my drinkin' with the boys。〃
With a jerk of his head； he indicated Gus and Brockhurst who were already at the wine。 Tanda was waiting for me with Aahz。 That made my choice a little easier。
〃Okay； Ajax；〃 I smiled。 〃I'll catch up with you in a little bit。〃
〃Congratulations； handsome！〃 Tanda winked as I joined them。 〃That was as neat a bit of work as I've seen in a long time。〃
〃Thanks； Tanda；〃 I blushed。
〃I see you and Ajax are on speaking terms again；〃 Aahz said； regarding me with cocked eyebrows。 〃That's not a bad trick in itself。 How did you do it？〃
〃We 。 。 。 um 。 。 。 we had a long talk；〃 I replied vaguely。 〃You said we had some planning to do？〃
〃More like a briefing；〃 Aahz admitted。 〃Tanda here brought along a few special effects items I think you should know about。〃
I had pletely forgotten about Tanda's errand which had left me alone at the Bazaar。 Now that I had been reminded； my curiosity soared。
〃Whatcha got； Tanda？〃 I asked eagerly。
〃Nothing spectacular；〃 she shrugged。 〃Knowing Aahz was involved； I figured we'd be on a tight budget so I stuck to the basics。〃
〃Just show him； huh？〃 Aahz growled。 〃Spare us the editorial ments。〃
She stuck her tongue out at him but produced a small cloth sack from her belt。
〃First off；〃 she began； 〃I thought we could use a little flash powder。 It never fails to impress the yokels。〃
〃Flash powder；〃 I said carefully。
〃You set fire to it；〃 Aahz supplied。 〃It burns fast and gives you a cloud of smoke。〃
〃I've got about a dozen small bags of it here；〃 Tanda continued； showing me the contents of her sack。 〃Various colors and sizes。〃
〃Can I try one？〃 I asked。 〃I've never worked with this stuff before。〃
〃Sure；〃 Tanda said。 She grinned； extending the sack。 〃They're yours to use as you see fit。 You might as well know what you've got。〃
I took the sack and carefully selected one of the small bags from its interior。
〃Better toss it to the ground； kid；〃 Aahz cautioned。 〃Some folks can set it off in their hand； but that takes practice。 If you tried it that way now； you'd probably lose a few fingers。〃
I'd obediently tossed the bag on the ground a few feet away。 Watching it curiously； I focused a quick burst of energy on it。
There was a bright flash of light acpanied by a soft pop。 Blinking my eyes； I looked at where the bag had been。 A small cloud of green smoke hung in the air； slowly dissipating in the breeze。
〃That's neat！〃 I exclaimed； reaching into the sack again。
〃Take it easy；〃 Aahz warned。 〃We don't have that much of the stuff。〃
〃Oh！ Right； Aahz；〃 I replied； feeling a little sheepish。 〃What else do you have； Tanda？〃
〃Well；〃 she said； smiling； 〃I guess this would be a piece…de…resistance。〃
As she spoke； she seemed to draw something from behind her back。 I say 〃seemed〃 because I couldn't see anything。 From her movements； she looked to be holding a rod about three feet long； but there was nothing in her grasp。
〃What is it？〃 I asked politely。
For a response； she grinned and held whatever it was in front of her。 Then she opened her grip and disappeared into thin air。
〃Invisibility；〃 Aahz exclaimed。 〃A cloak of invisibility！〃
〃Couldn't afford one；〃 came Tanda's voice from somewhere in front of us。 〃I had to settle for one of these。〃
What 〃one of these〃 was； it turned out； was a sheet of invisibility。 It was a sheet of stiff material about three feet by seven feet。 Tanda had been carrying it rolled up in a tube； and her disappearance had been caused by the sheet unrolling to its full size。
As she and Aahz chatted excitedly about her new find； I had an opportunity to further my knowledge in the field of invisibility。
Invisible sheets； it seems； were made of roughly the same material as invisible cloaks。 Since the sheets were carried； not worn； they did not require the flexibility and softness necessary for a cloak。 Consequently； they were considerably cheaper than the cloaks。
The effect was sort of like one…way glass。 When you were on the right side of an invisible sheet； you could see through it perfectly well to observe whatever or whoever was on the other side。 They； however； could not see you。
We were still discussing the potential uses of the new tool when Brockhurst hastened up to our group。
〃Hey； boss！〃 he called。 〃We've got pany！〃
〃Who？ Where？〃 I asked calmly。
〃Down on the meadow；〃 the Imp responded； pointing。 〃The
