Mustang Rock. Pollo put a finger to her mouth, signalling to hush. Shoulders to the looming granite wall, they skirted around to a cleared area in front of the dark arch of cave and peeked. But no one was lying in wait.
A narrow, overgrown trail led off the clearing. Will plucked at a prickle on his arm. âPollo, does that track lead to Diamond Jackâs Trail, by any chance?â
Pollo shrugged. âMaybe.â
âYou mean, Iâve got more holes than a cheese grater from climbing through all those spiky bushes, and we could have strolled along a nice shady track? âWe just swing by Mustang Rock on the way,â you said! You didnât say the
back
way.â
âWe couldnât risk running into those two on the main trail, could we?â said Pollo. âA good investigator always thinks ahead, Will.â
âBut I suppose,â said Dan, âif we
had
happened to run into them, they donât know that we know anything. We could have just pretended to be bushwalkers.â
Pollo looked sheepishly at Will. âI didnât think of that.â
Will rolled his eyes and huffed.
Suddenly Ash whipped forward, covering her mouth.
Eew-chew!
Birds flapped from their hiding places in the trees.
Eew-chew!
Leaves fluttered to the ground. âTheyâve been here alright,â sniffled Ash, a finger pressed sideways under her nose. âThat aftershave! I donât think weâve missed them by much.â
Dan jigged from one foot to the other. âWe should be really quiet then ⦠donât you all think?â
âSo they
did
get down there from here,â said Pollo.
âEven though the tunnelâs blocked off?â said Dan.
âI guess they unblocked it,â said Will. âLetâs take a look.â
They entered the dank, dark mouth of Mustang Rock, their breathing shallower with the musty smell. At the back of the cave, a natural chimney threw light on a patch of ground. Nearby was the tunnel entrance,blocked by a heavy iron grid. The grid was blackened with age and pitted from years of constant damp. Tiny hairs of bright green moss sprouted on its bars. A large padlock and thick chain hung from one side.
âThere are shiny scratches around the keyhole!â said Pollo. âJust as I suspected!â
âMayor Bullock must have given them a key,â said Ash.
âHeâs up to something fishy, alright,â said Pollo. âWhy else would he give keys to two dodgy people who donât care two hoots about either caves or safety regulations?â
Pollo began pacing back and forth, tapping her fingertips together. âThat lock looks pretty rusty. Maybe if we got a big rock we could just ââ
âI know what youâre thinking and you can unthink it!â said Will. âWeâre not going down there! Iâm starving to death! Someone ate all the sandwiches, remember?â
âPretend youâre fasting,â said Pollo, âlike one of those monks. Ash, how about you?
âIâll keep guard, but I wonât go underground again. The thought I kept having in the other cave of something going wrong, of becoming trapped â¦â Ashâs whole body shuddered. âItâs still haunting me.â
âOkay,â said Pollo. âI wonât push you.â
âWow!â said Will. âWhenever I say no to Pollo she ignores me.â
âYouâve got to mean it,â said Ash.
Will thought a moment. Maybe Ash had something there.
âIâll go with you, Pollo,â said Dan. âGee willakers, itâs not like Iâm busting to go home right now. Twig and his portals! Until I can show him the bushrangersâ cave Iâm steering clear.â
âIâd like to meet Twig,â said Ash solemnly. âHeâs curious about the types of things most of us donât question. Hey, my mumâs working backstage in a play at the Town Hall
