〃Wouldn't have missed it for the world；〃 Marjorie agreed。
〃Drive us around awhile； slowly；〃 Sally told the coachman as they got in。 〃It's a shame to go back to the hotel so soon。 Isn't it beautiful out here in the moonlight？〃
〃Don't let's run up too big a bill；〃 Marjorie cautioned。
〃Forget it； this is my night。 What's a vacation for anyway？〃 An empty side lane had opened out beside them。 〃Turn up that way；〃 she ordered the driver。 〃Take us off this main driveway； it's too full of exhaust fumes from all the traffic。〃
There wasn't another vehicle in sight on it。 It stretched barren into the night； in a ruler…straight line before them。
〃There； isn't this much better？ We've got it all to ourselves；〃 said the headstrong Sally。 〃I like to explore new roads； don't you？〃
〃I can take them or leave them alone；〃 Marjorie had to admit。 It was just a little too lifeless to appeal to her； but she didn't like to spoil her friend's good time。
It began to curve slowly around to the left presently； and as it did so； a sheet of burnished silver； glistening like a mirror under the moon； came into view through the trees。
〃Look at that lake with the swans on it！〃 Sally enthused。 〃Did you ever see anything so exquisite？〃
The horse was going at a slow walk。 Presently the trees between it and them had thinned to extinctiOn； and only a grassy； downward slope lay between the road and it。 〃Let's get Out and walk down to the edge of it；〃 was Sally's next suggestion。 〃Stretch our legs a little after sitting so long。 I love to walk along beside water； don't you？〃
〃Not at this hour of the night；〃 Marjorie said halfheartedly。 〃Let's turn around and go back where there are more people。 It's getting late； and we're awfully far in…〃
〃Don't be that way。 You're a big girl now。 Nothing can happen to us as long as we stay in sight of the coach； don't go roaming too far off。 I promise you we won't let it out of our sight。〃 She already had one foot poised out of the carriage。
Marjorie gave in once more； but this time it was the coachman who began to jabber objections to them when he saw them about to descend。
〃What's he saying？〃 asked Marjorie。
〃just about what everyone else has been； I guess。 Advising us not to leave the carriage and go walking around on foot； most likely。 I think it's a conspiracy on the part of everyone。 These high…strung Latins！〃
〃They live here； after all；〃 Marjorie pointed out。
But the impulsive little redhead hadn't waited； was already picking her way down the gently inclined sward toward the lake below； flashing blindingly in the moonlight。 Marjorie turned to the driver； warned him with one Spanish word and a dozen English ones； her usual ratio： 〃 Espera。 Don't you dare budge from here； understand？ We'll be back in a minute。〃
He nodded in disapproving acquiescence； but the horse； meanwhile； was pawing the ground uneasily and shifting about between the traces。 He had to tighten his grip on the reins to steady it。 She saw its ears standing stiffly erect； as though it heard or sensed something that the humans about it were still unaware of。
〃Sal；〃 she called down the slope。 〃I think we'd better get back in again。 I don't like the way this horse is acting。〃 But even the attempt to overrule her friend and bring her back again； in itself； was carrying her involuntarily down toward the water's edge herself。
Sally had already reached it； was crouched there on her heels； crumbling some after…dinner wafers she had brought along from the restaurant and holding them out enticingly toward a flotilla of magnificent black swans； who came streaking up from all directions。 〃Aren't they beauts？〃 she called obviously over her shoulder。 〃C'mon down； what're you afraid of？〃
Marjorie made her way down to her； still only to persuade her to e back。 〃e on； Sal；〃 she said reasonably。 〃Something's making that horse fidget up there。 Let's get out of here。〃
〃Oh； it probably just wants to get back to the stable； you know how horses are。〃 She went on paying out crumbs。 〃Look at them fight one another。 That's what you call muscling in！〃
Suddenly they all began to reverse； dart out into the middle of the lake again as swiftly as they had drawn shoreward just now。
〃What's the matter with them； what're they doing that for？〃 Sally asked blankly。
〃Something's frightened them…and it wasn't ourselves。 They were practically snatching those crumbs out of your hand a minute before。 I told you we'd better get out of here！〃 She began pulling the other girl insistently by the arm to get her to e away。 〃This is just the sort of place we were warned to stay away from。〃
〃Oh； all right；〃 Sally said weariedly。 She straightened her feet and brushed the front of her dress。 〃Don't be such a wet blanket。〃
They turned to face the roadway up above once more； just in time to witness the horse rearing violently upward on its hind legs until it was nearly vertical within its traces。 It whinnied with shrill fearfulness。 The coachman； nearly overturned； gave an alarmed shout。 The animal dropped back again； sparks flashing out from its shoes； and then it plunged forward； bolting off under their very eyes while they stood there rooted helplessly to the spot。 In another moment the rapid clatter of its hoofbeats and the driver's excited yells had both alike died away far down the driveway。
They came running up to the edge of it a moment later； stood there aghast； looking down its empty moon…speckled length。 A little blue dust； siowly settling in places from the vehicle's headlong flight； was the only trace left of it。
Marjorie's hands struck her sides； rebounded again。 〃 Now are you satisfied？〃 she said pointedly。 〃You would get out and leave it。〃
〃How did I know that was going to happen？ He'll get him under control in a minute or two and e back to get us。 That's the only way he can get his money for the whole night's excursion。〃
Marjorie； however； wasn't taking such a calm view of it。 〃Well； we're not waiting around here until he does！〃 she let her panion know sharply。 〃There's something around here that there shouldn't be； and I know what I'm saying。 First the swans； and then that horse…〃
They started to walk briskly along by the side of the road； following in the same direction the runaway horse had taken。 Even though they had no idea where the road led； to keep on along it was their only hope of meeting the carriage again on its return trip。
They were alternately in shadow and moonlight。 The macadam surface was hard on their feet after a while； in the thin…soled evening slippers they were wearing。 First one； then the other； changed over to the turf on the outside of the roadway； where the walking was easier。 This brought them into single file； however； for trees； tree roots3 and bushes impinged quite closely on the road strip in places。 Marjorie was in the lead。
Their tread fell silently on the soft earth now。 It was when they had been doing this for several minutes that they first became aware of something。 A soft intermittent rustling sound； a sort of whispering slither； was ing from the foliage a little behind and off to one side of them。 It seemed to be pacing them。 It was very subtle； scarcely anything at all。 It would stop and then go on again。
Marjorie hung back a step； so she could whisper over her shoulder to the girl behind her without raising her voice。 〃Do you hear that？〃 she breathed。 〃Something…or someone…is following us through there。 I told you there was something around here there shouldn't be…〃
They'd both stopped short； instinctively； in order to listen the better。 But now the sound itself had stopped too； as if suiting its actions to theirs。 There was an interval of throbbing silence。 Then a twig snapped betrayingly； as if slowly crushed in twain under something's arrested weight。
All Sally's former nonchalance had left her by now。 〃Oh； why didn't I listen to you！〃 she whimpered。 She gave her friend a push forward。 〃Don't let's stand here waiting for it； whatever it is！ Run； quick！ Let's get out of here！〃
With one accord they fled swiftly down the side of the long； heartlessly empty road； again one behind
