He spoke sharply, with the deliberate intent of rousing her; but, as she only smiled and blinked, he prompted:
'You said that you had a communication of some sort you wished to make?'
'Dear Sir Henry. And you-and you-' After a pause she took one hand off her cane and put her fingers gently on his desk. 'Are you all blind?'
'Blind, ma'am?'
'Do you mean that clever men like you - and you - haven't seen? Must I tell you? Do you really mean that you don't know why dear Theodore left town and rushed away to his mother in that mad hurry? Either out of fear, or in case he should have to tell what he might not wish to tell? Don't you know what he guessed, and now he knows?'
H.M.'s dull eyes flickered open. She leaned abruptly towards him. Her voice was still low, but it was as though another of Darworth's ghoulish toys say a fantastic, unholy jack-in-the-box-had snapped open.
'That Marion Latimer is mad,' said Lady Benning.
Silence....
'Oh, I know!' She spoke more sharply, and peered at us. 'I know how you would be deceived. You think that because a girl is young, and pretty, and can laugh at your man's jokes, and goes swimming and diving and playing tennis on two strong legs, that there can't be any maggot up here. Don't you? Don't you?' she demanded, and her glance flickered round again. 'You wouldn't hesitate to believe it of me, though. And why? Because I am old, and because I believe things you are simply too blind to see. That's why; that's the only reason.
'All the Melishes are rotten with insanity. I could have told you that. Sara Melish, that girl's mother, is kept under observation in Edinburgh.... But if you won't believe what I tell you, won't you believe plain evidence?'
'Humph. Such as-?'
'The voice in Ted's room that morning!' She apparently caught some expression on H.M.'s face, for she kept smiling and nodding. 'Why did you all so easily assume it was an outsider? Was it likely that an outsider should be on the balcony at that hour of the morning? But, you see, the balcony runs all around the house: past dear Marion's bedroom.... But was it a wonder that a poor kitchen-maid was deceived in the voice? Dear Sir Henry, she had never heard it before-speaking in that manner. That was the dear girl's real voice. What else can one make of the words, `You never suspected it, did you?'
I heard hard breathing behind me. Masters lumbered past and up to H.M.'s desk.
'Ma'am,' he said, 'ma'am'
'Shut up, Masters,' said H.M. softly.
'And that dear gullible police-sergeant of yours, that Mr. McDonnell you sent to spy on us before,' continued Lady Benning, lifting and lowering her fingers on the desk. Her painted face moved snakily around. 'He called on poor Marion at an inconvenient hour yesterday afternoon. She got rid of him - oh, so easily, the dear clever girl! She had to go out. Oh, yes. She had other work to do.'
Lady Benning giggled. Then her head jerked up.
'I believe the inquest is to be held this afternoon, Sir Henry. I shall perform my duty. I shall go into the box and accuse poor Marion of the murder of Roger Darworth and of Joseph Dennis.'
The silence after those sharply enunciated words was broken by H.M:'s thoughtful voice: 'Now, ma'am, that's most interestin'. You won't be able to do, it this afternoon, of course; I forgot to tell you there's been an adjournment---'
She leaned again. It was like a pounce. 'Ah! You believe me, don't you? I can see it in your face. Dear Sir Henry... . '
'But it's interestin'. It shows rather a change of attitude, don't it? I wasn't there, and all I know is what I read, but didn't you say Darworth had got himself done in by ghosts?'
Her little eye gleamed like a crumb of glass. Say that, and you touch the fanatic. 'Make no mistake, my friend. If they had chosen to kill Mr. Darworth- '
There was a late and somnolent fly drumming along the edge of H.M.'s desk. Her black-gloved hand shot out. The next moment she brushed the dead thing softly to the carpet; then she dusted her hands together, smiled at H.M., and went on evenly: 'That is why I supposed it, you see. But when the unfortunate imbecile was murdered, I knew that they had only stood by in their power, and watched a human being commit these murders. In a way, it was their direction. Oh, yes. They were instrumental. But they chose a human agent.' Slowly she lifted herself across his desk; and, leaning nearly in his face, scrutinized H.M. with a hideous earnestness. 'You do believe me? You do believe me, don't you?'
H.M. rubbed his forehead. 'It seems to me, now that I remember it, something about Miss Latimer and Halliday holdin' hands. . .
She was a wise general. She knew the value of not saying too much; she knew the value of her effects. After carefully watching H.M.'s face-and, in general, card-players have found this a highly unprofitable proceeding - she seemed satisfied. There was a thin frosty light of triumph about her. She got to her feet, and so did H.M. and I.
'Good-by, dear Sir Henry,' she said softly, at the door. 'I shall not take up your time. And holding hands?' She giggled again, raised her hand and wagged a finger at us. 'Surely my dear nephew is chivalrous enough to uphold her if she cares to say that? It is the simple conduct of a gentleman. Besides, you know, he may have been deceived.' Her face assumed a sly and coquettish simper. 'Who knows? In her absence, he may have been holding mine.'
The door closed. We heard the cane slowly tap-tapping down the hall.
'Sit still!' said H.M., as Masters made a movement forward. His command rang in the ugly quiet. 'Be still, you fool. Don't go after her.'
'My God,' said Masters, 'do you mean to tell me she's right?'
'I'm only tellin' you we've got to work fast, son. Take a chair. Light a cigar. Be calm.' He hoisted his feet on the desk again, and drowsily blew smoke-rings. 'Look here, Masters. Did you have any suspicions of the Latimer girl?'
'I'll be honest about it, sir. I never even considered it.'
'That's bad. On the other hand, y'see, the mere fact that she was the farthest from suspicion don't necessarily mean she's guilty. Things'd be too easy like that. Find the unlikeliest person - call the Black Maria. The trap is that, since it don't seem likely, you'll believe it all the more. Besides, in this case it happens to be the most likely one who's guilty....
'But who is the most likely one?'
H.M. chuckled. 'That's been the trouble with the case; we haven't been able to see it. Still, at my little party tonight ... by the way, you didn't know about it, did you, Ken? Plague Court at eleven o'clock sharp. This will be strictly stag. I want you, and young Halliday, and Bill Featherton.... Masters, you're not to be with us; I'll give you your instructions presently. I'll need some extra men for help, but they'll come from my own department. Shrimp's the man I want, if I can find him.'
'All right,' the Inspector agreed wearily. 'Whatever you say, sir. If you'll agree to introduce me to the murderer, I'll do anything in this nightmare of a business. I'm just about crazy, and that's a fact. After that fiasco of Mrs. Sweeney '
'You know about it?' I interrupted, and hastened to lay out my information. Masters nodded.
'Every time we get a lead,' he said, 'even a small one, it's cut out almost as soon as it's mentioned.... Yes, I know. That was Durrand's brain-wave. That was the reason he dragged me in with a trunk-call from Paris that we had to pay for. He found out about Glenda Darworth; and then that there were long periods when she was not seen in Nice. I'll admit he got me excited about the thing.... H.M. waved his cigar in the air.
'Burn me,' he said admiringly, 'Masters was inspired with a real joie de vivre, he was. Back he goes to Magnolia Cottage a-flying, with a female searcher in tow. So they leap on Mrs. Sweeney with triumphant shouts, and then they discover that something's wrong. No padding. No wig....”
'But, blast it,, the woman isn't young any more,' Masters protested; 'she mightn't have needed any disguise-'
H.M. pushed over the copy of
