Say it's the fifth post from the end。 Well； then I take a line from my tree
we'll find one for me directly and it comes on to the twentieth post； say。
And where the two lines meet； there shall the eagles be gathered together。
Q。E。D。 And there； I almost forgot to remark； will the taller eagle；
Beverley by name； do his famous diving act。 As performed nightly at the
Hippodrome。〃
Bill looked at him uneasily。
〃I say； really？ It's beastly dirty water； you know。〃
129
The Red House Mystery
〃I'm afraid so； Bill。 So it is written in the book of Jasher。〃
〃Of course I knew that one of us would have to； but I hoped； well； it's
a warm night。〃
〃Just the night for a bathe；〃 agreed Antony； getting up。 〃Well now；
let's have a look for my tree。〃
They walked down to the margin of the pond and then looked back。
Bill's tree stood up and took the evening； tall and unmistakable； fifty feet
nearer to heaven than its neighbours。 But it had its fellow at the other
end of the copse； not quite so tall； perhaps； but equally conspicuous。
〃That's where I shall be；〃 said Antony； pointing to it。 〃Now； for the
Lord's sake； count your posts accurately。〃
〃Thanks very much； but I shall do it for my own sake；〃 said Bill with
feeling。 〃I don't want to spend the whole night diving。〃
〃Fix on the post in a straight line with you and the splash； and then
count backwards to the beginning of the fence。〃
〃Right； old boy。 Leave it to me。 I can do this on my head。〃
〃Well； that's how you will have to do the last part of it；〃 said Antony
with a smile。
He looked at his watch。 It was nearly time to change for dinner。 They
started to walk back to the house together。
〃There's one thing which worries me rather；〃 said Antony。 〃Where
does Cayley sleep？〃
〃Next door to me。 Why？〃
〃Well； it's just possible that he might have another look at you after
he's come back from the pond。 I don't think he'd bother about it in the
ordinary way； but if he is actually passing your door； I think he might
glance in。〃
〃I shan't be there。 I shall be at the bottom of the pond； sucking up
mud。〃
〃Yes。。。。 Do you think you could leave something in your bed that
looked vaguely like you in the dark？ A bolster with a pyjama…coat round
it； and one arm outside the blanket； and a pair of socks or something for
the head。 You know the kind of thing。 I think it would please him to
feel that you were still sleeping peacefully。〃
130
The Red House Mystery
Bill chuckled to himself。
〃Rather。 I'm awfully good at that。 I'll make him up something
really good。 But what about you？〃
〃I'm at the other end of the house； he's hardly likely to bother about me
a second time。 And I shall be so very fast asleep at his first visit。 Still； I
may as well to be on the safe side。〃
They went into the house。 Cayley was in the hall as they came in。 He
nodded； and took out his watch。
〃Time to change？〃 he said。
〃Just about；〃 said Bill。
〃You didn't forget my letter？〃
〃I did not。 In fact； we had tea there。〃
〃Ah！〃 He looked away and said carelessly； 〃How were they all？〃
〃They sent all sorts of sympathetic messages to you； and and all that
sort of thing。〃
〃Oh； yes。〃
Bill waited for him to say something more； and then； as nothing was
coming； he turned round； said； 〃Come on； Tony；〃 and led the way upstairs。
〃Got all you want？〃 he said at the top of the stairs。
〃I think so。 Come and see me before you go down。〃
〃Righto。〃
Antony shut his bedroom door behind him and walked over to the
window。 He pushed open a casement and looked out。 His bedroom was
just over the door at the back of the house。 The side wall of the office；
which projected out into the lawn beyond the rest of the house； was on his
left。 He could step out on to the top of the door； and from there drop
easily to the ground。 Getting back would be little more difficult。 There
was a convenient water…pipe which would help。
He had just finished his dressing when Bill came in。 〃Final
instructions？〃 he asked； sitting down on the bed。 〃By the way； how are
we amusing ourselves after dinner？ I mean immediately after dinner。〃
〃Billiards？〃
〃Righto。 Anything you like。〃
〃Don't talk too loud；〃 said Antony in a lower voice。 〃We're more or
131
The Red House Mystery
less over the hall； and Cayley may be there。〃 He led the way to the
window。 〃We'll go out this way to…night。 Going downstairs is too risky。
It's easy enough； better put on tennis…shoes。〃
〃Right。 I say； in case I don't get another chance alone with you what
do I do when Cayley comes to tuck me up？〃 〃It's difficult to say。 Be as
natural as you can。 I mean； if he just knocks lightly and looks in； be
asleep。 Don't overdo the snoring。 But if he makes a hell of a noise；
you'll have to wake up and rub your eyes； and wonder what on earth he's
doing in your room at all。 You know the sort of thing。〃
〃Right。 And about the dummy figure。 I'll make it up directly we
come upstairs； and hide it under the bed。〃
〃Yes。。。。 I think we'd better go completely to bed ourselves。 We shan't
take a moment dressing again； and it will give him time to get safely into
the passage。 Then come into my room。〃
〃Right。。。。 Are you ready？〃
〃Yes。〃
They went downstairs together。

The Red House Mystery
CHAPTER XVII
Mr。 Beverley Takes the Water
Cayley seemed very fond of them that night。 After dinner was over；
he suggested a stroll outside。 They walked up and down the gravel in
front of the house； saying very little to each other； until Bill could stand it
no longer。 For the last twenty turns he had been slowing down hopefully
each time they came to the door； but the hint had always been lost on his
companions； and each time another turn had been taken。 But in the end
he had been firm。
〃What about a little billiards？〃 he said； shaking himself free from the
others。
〃Will you play？〃 said Antony to Cayley。
〃I'll watch you；〃 he said； and he had watched them resolutely until the
game； and then another game after that； had been played。
They went into the hall and attacked the drinks。
〃Well； thank heaven for bed；〃 said Bill； putting down his glass。 〃Are
you coming？〃
〃Yes；〃 said Antony； and finished his drink。 He looked at Cayley。
〃I've just got one or two little things to do；〃 said Cayley。 〃I shan't be
long following you。〃
〃Well； good night； then。〃
〃Good night。〃
〃Good night；〃 called Bill from half…way up the stairs。 〃Good night；
Tony。〃
〃Good night。〃
Bill looked at his watch。 Half…past eleven。 Not much chance of
anything happening for another hour。 He pulled open a drawer and
wondered what to wear on their expedition。 Grey flannel trousers；
flannel shirt； and a dark coat； perhaps a sweater； as they might be lying out
in the copse for some time。 And good idea a towel。 He would want it
later on； and meanwhile he could wear it round his waist。
Tennis…shoes。。。。 There Everything was ready。 Now then for the
dummy figure。
133
The Red House Mystery
He looked at his watch again before getting into bed。 Twelve…fifteen。
How long to wait before Cayley came up？ He turned out the light； and
then； standing by the door in his pyjamas； waited for his eyes to become
accustomed to the new darkness。。。。 He could only just make out the bed in
the corner of the room。 Cayley would want more light than that if he
were to satisfy himself from the door that the bed was occupied。 He
pulled the curtains a little way back。 That was about right。 He could
have another look later on； when he had the dummy figure in the bed。
How long would it be before Cayley came up？ It wasn't that he
wanted his friends； Beverley and Gillingham； to be asleep before he
started on his business at the pond； all that he wanted was to be sure that
they were safely in their bedrooms。 Cayley's business would make no
noise； give no sign； to attract the most wakeful member of the household；
so long as the household was really inside the house。 But if he wished to
reassure himself about his guests； he would have to wait until they were
far enough on their way to sleep not to be disturbed by him as he came up
to reassure himself。 So it amounted to the same thing； really。 He would
wait until they were asleep。。。。 until they were asleep 。。。。 asleep。。。。
With a great effort Bill regained the mastery over his wandering
thoughts and came awake again。 This would never do。 It would be
fatal if he went to sleep。。。。 if he went to sleep。。。。 to sleep。。。。 And then； in an
instant； he was intensely awake。 Suppose Cayley never came at all！
Suppose Cayley was so unsuspicious that； as soon as they had gone
upstairs； he had dived down into the passage and set about his business。
Suppose； even now； he was at the pond； dropping into it that secret of his。
Good heavens； what fools they had been！ How could Antony have taken
such a risk？ Put yourself in Cayley's place； he had said。 But how was it
possible？ They weren't Cayley。 Cayley was at the pond now。 They
would never know what he had dropped into it。
Listen！。。。。 Somebody at the door。 He was asleep。 Quite naturally
now。 Breathe a little more loudly； perhaps。 He was asleep。。。。 The door
was opening。 He could feel it opening behind him。。。。 Good Lord；
suppose Cayley really was a murderer！ Why； even now he might be … no；
he mustn't think of that。 If he thought of that； he would have to turn
134
The Red House Mystery
round。 He mustn't turn round。 He was asleep； just peacefully asleep。
But why didn't the door shut？ Where was Cayley now？ Just behind
him？ And in his hand no； he mustn't think of that。 He was asleep。 But
why didn't the door shut？
The door was shutting。 There was a sigh from the sleeper in the bed；
a sigh of relief which escaped him involuntarily。 But it had a very
natural sound a deep breath from a heavy sleeper。 He added another one
to it to make it seem more natural。 The door was shut。
Bill counted a hundred slowly and then got up。 As quickly and as
noiselessly as possible he dressed himself in the d
