ng with extraordinary cunning and intelligence； and we should probably have caught him long ago； were it not that he managed； when on his way out of the place； to annex a considerable sum of money in gold； with which the wages of the asylum staff were about to be paid。 It is owing to that fact that his escape was。 very wrongly； concealed … 〃
He stopped abruptly； as if sorry he had said so much； and a moment later the party were walking in Indian file through the turnstile； Sir John Burney leading the way。
Mrs。 Bunting looked straight before her。 She felt … so she expressed it to her husband later … as if she had been turned to stone。
Even had she wished to do so； she had neither the time nor the power to warn her lodger of his danger； for Daisy and her companion were now coming down the room； bearing straight for the Commissioner of Police。 In another moment Mrs。 Bunting's lodger and Sir John Burney were face to face。
Mr。 Sleuth swerved to one side； there came a terrible change over his pale； narrow face； it became discomposed； livid with rage and terror。
But； to Mrs。 Bunting's relief … yes； to her inexpressible relief … Sir John Burney and his friends swept on。 They passed Mr。 Sleuth and the girl by his side； unaware； or so it seemed to her； that there was anyone else in the room hut themselves。
〃Hurry up； Mrs。 Bunting；〃 said the turnstile…keeper； 〃you and your friends will have the place all to yourselves for a bit。〃 From an official he had become a man； and it was the man in Mr。 Hopkins that gallantly addressed pretty Daisy Bunting： 〃It seems strange that a young lady like you should want to go in and see all those 'orrible frights；〃 he said jestingly。
〃Mrs。 Bunting； may I trouble you to come over here for a moment？〃
The words were hissed rather than spoken by Mr。 Sleuth's lips。
His landlady took a doubtful step towards him。
〃A last word with you； Mrs。 Bunting。〃 The lodger's face was still distorted with fear and passion。 〃Do not think to escape the consequences of your hideous treachery。 I trusted you； Mrs。 Bunting； and you betrayed me！ Put I am protected by a higher power； for I still have much to do。〃 Then； his voice sinking to a whisper； he hissed out 〃Your end will be bitter as wormwood and sharp as a two…edged sword。 Your feet shall go down to death； and your steps take hold on hell。〃
Even while Mr。 Sleuth was muttering these strange； dreadful words； he was looking round； glancing this way and that； seeking a way of escape。
At last his eyes became fixed on a small placard placed above a curtain。 〃Emergency Exit〃 was written there。 Mrs。 Bunting thought he was going to make a dash for the place； but Mr。 Sleuth did something very different。 Leaving his landlady's side； he walked over to the turnstile； he fumbled in his pocket for a moment； and then touched the man on the arm。 〃I feel ill；〃 he said； speaking very rapidly； 〃very ill indeed！ It is the atmosphere of this place。 I want you to let me out by the quickest way。 It would be a pity for me to faint here … especially with ladies about。〃
His left hand shot out and placed what he had been fumbling for in his pocket on the other's bare palm。 〃I see there's an emergency exit over there。 Would it be possible for me to get out that way？〃
〃Well； yes； sir； I think so。〃
The man hesitated； he felt a slight； a very sight； feeling of misgiving。 He looked at Daisy； flushed and smiling； happy and unconcerned； and then at Mrs。 Bunting。 She was very pale； but surely her lodger's sudden seizure was enough to make her feel worried。 Hopkins felt the half …sovereign pleasantly tickling his palm。 The Paris Prefect of Police had given him only half…a…crown … mean； shabby foreigner！
〃Yes； sir； I can let you out that way；〃 he said at last； 〃and p'raps when you're standing out in the air； on the iron balcony； you'll feel better。 But then； you know； sir； you'll have to come round to the front if you wants to come in again； for those emergency doors only open outward。〃
〃Yes； yes；〃 said Mr。 Sleuth hurriedly。 〃I quite understand！ If I feel better I'll come in by the front way； and pay another shilling … that's only fair。〃
〃You needn't do that if you'll just explain what happened here。〃
The man went and pulled the curtain aside； and put his shoulder against the door。 It burst open； and the light； for a moment； blinded Mr。 Sleuth。
He passed his hand over his eyes。 〃Thank you；〃 he muttered； 〃thank you。 I shall get all right out there。〃
An iron stairway led down into a small stable yard； of which the door opened into a side street。
Mr。 Sleuth looked round once more； he really did feel very ill … ill and dazed。 How pleasant it would be to take a flying leap over the balcony railing and find rest； eternal rest； below。
But no … he thrust the thought the temptation； from him。 Again a convulsive look of rage came over his face。 He had remembered his landlady。 How could the woman whom he had treated so generously have betrayed him to his arch…enemy？ … to the official； that is； who had entered into a conspiracy years ago to have him confined … him； an absolutely sane man with a great avenging work to do in the world … in a lunatic asylum。
He stepped out into the open air； and the curtain； falling…to behind him； blotted out the tall； thin figure from the little group of people who had watched him disappear。
Even Daisy felt a little scared。 〃He did look bad； didn't he； now？〃 she turned appealingly to Mr。 Hopkins。
〃Yes； that he did； poor gentleman … your lodger； too？〃 he looked sympathetically at Mrs。 Bunting。
She moistened her lips with her tongue。 〃Yes；〃 she repeated dully； 〃my lodger。〃
CHAPTER XXVII
In vain Mr。 Hopkins invited Mrs。 Bunting and her pretty stepdaughter to step through into the Chamber of Horrors。 〃I think we ought to go straight home；〃 said Mr。 Sleuth's landlady decidedly。 And Daisy meekly assented。 Somehow the girl felt confused； a little scared by the lodger's sudden disappearance。 Perhaps this unwonted feeling of hers was induced by the look of stunned surprise and； yes； pain； on her step…mother's face。
Slowly they made their way out of the building； and when they got home it was Daisy who described the strange way Mr。 Sleuth had been taken。
〃I don't suppose he'll be long before he comes 〃home；〃 said Bunting heavily； and he cast an anxious； furtive look at his wife。 She looked as if stricken in a vital part； he saw from her face that there was something wrong … very wrong indeed。
The hours dragged on。 All three felt moody and ill at ease。 Daisy knew there was no chance that young Chandler would come in to…day。
About six o'clock Mrs。 Bunting went upstairs。 She lit the gas in Mr。 Sleuth's sitting…room and looked about her with a fearful glance。 Somehow everything seemed to speak to her of the lodger； there lay her Bible and his Concordance； side by side on the table； exactly as he had left chew； when he had come downstairs and suggested that ill…starred expedition to his landlord's daughter。 She took few steps forward； listening the while anxiously for the familiar sound of the click in the door which would tell her that the lodger had come back； and then she went over to the window and looked out。
What a cold night for a man to be wandering about； homeless； friendless； and； as she suspected with a pang； with but very little money on him！
Turning abruptly； she went into the lodger's bedroom and opened the drawer of the looking…glass。
Yes； there lay the much…diminished heap of sovereigns。 If only he had taken his money out with him！ She wondered painfully whether he had enough on his person to secure a good night's lodging； and then suddenly she remembered that which brought relief to her mind。 The lodger had given something to that Hopkins fellow … either a sovereign or half a sovereign； she wasn't sure which。
The memory of Mr。 Sleuth's cruel words to her； of his threat； did not disturb her overmuch。 It had been a mistake … all a mistake。 Far from betraying Mr。 Sleuth； she had sheltered him … kept his awful secret as she could not have kept it had she known； or even dimly suspected； the horrible fact with which Sir John Burney's words had made her acquainted； namely； that Mr。 Sleuth was victim of no temporary aberration； but that he was； and had been for years； a madman； a homicidal maniac。
In her ears there still rang the Frenchman's half careless yet confident question； 〃De Leipsic and Liverpool man？〃
Following a sudden impulse； she went back into the sitting…room； and taking a black…headed pin out of her bodice stuck it amid the leaves of the Bible。 Then she opened the Book； and looked at the page the pin had marked： …
〃My tabernacle is spoiled and all my cords are broken 。 。 。 There is none to stretch forth my tent any more and to set up my curtains。〃
At last leaving the Bible open； Mrs。 Bunting went downstairs； and as she opened the door of her sitting…room Daisy came towards her stepmother。
〃I'll go down and start getting the lodger's supper ready for you；〃 said the girl good…naturedly。 〃He's certain to come in when he gets hungry。 But he did look upset； didn't he； Ellen？ Right down bad … that he did！〃
