had been his blow that had killed it, though he had expressed regret for the beer. He murmured, 'It does. It is a crotalid, and one of the few snakes that will strike without challenge or warning. Only last week I was looking at a picture of it, in one of the books you procured for me. It is abundant throughout South America.'
'They found snake venom in Barstow.'
'Yes. That could have been suspected when the analysis was found difficult. The needle must have been well smeared. These considerations, Archie, will become of moment if Anna Fiore fails us and we must have recourse to a siege. Many things will be discoverable with sufficient patience and-well, abandonment of reserve. Is there somewhere on the Kimball estate a pit where Manuel has carried rats to his fer-de-lance? Did he extract the venom himself by teasing its bite into the pulp of a banana? Unlikely. Has he an Argentine friend who sent the poison to him? More likely. The young man-dark and handsome, Fritz says-who brought the note not from Miss Barstow, and who is admirably deft with vipers, will he be found to be on duller days an usher in a 116th Street movie theater? Or a seaman on a South American boat, providentially arrived at the port of New York only yesterday? Difficult questions, but each has its answer, if it comes to a siege. It is likely that Manuel Kimball arranged some time ago for the journey of the fer-de-lance, as a second string to his bow; thinking that if the contrivance designed by man should for any reason fail it would be well to give nature’s own mechanism a chance. Then, when it arrived, there was a more urgent need for it; vengeance stepped back for safety. And now, to this moment at least, he has neither.'
'Maybe. But he just barely missed getting one, and he may get the other any minute.'
Wolfe wiggled a finger at me. 'Faulty, Archie, inexcusably faulty. Vengeance will continue to wait. Mr. Manuel Kimball is not a creature of impulse. Should circumstances render him suddenly desperate he would act with desperation, but even then not impulsively.-But Miss Maffei is due in half an hour, and you should know the arrangements before she arrives. Your notebook.'
I got at my desk, and he dictated twenty minutes without stopping. After the first two minutes I put on a grin, and kept it on till the end. It was beautiful, it was without a flaw, and it covered every detail. He had even allowed for Maria Maffei’s refusal or her inability to persuade Anna; in that case the action was approximately the same, but the characters were shifted around; I was to take it with Anna. He had telephoned Burke Williamson and arranged for a clear stage for us, and Saul Panzer was to call at the office at six o’clock for the sedan and his instructions. When he had finished dictating it was all so clear that there were few questions for me to ask. I asked those few, and ran back over the pages. He was leaning back in his chair, full of beer, pretending he wasn’t pleased with himself.
I said, 'All right, I admit it, you’re a genius. This will get it if she’s got it.'
He nodded without concern.
Maria Maffei arrived on the dot. I was waiting for her on my toes and got to the door before Fritz was out of the kitchen. She was dressed in black, and if I had met her on the street I doubt if I would have known her, she looked so worn out. I was so full of Wolfe’s program that I had a grin ready for her, but I killed it in time. She wasn’t having any grins. After I saw her I didn’t feel like grinning anyway; it sobered me up to see what the death of a brother might do to a woman. She was ten years older and the bright life in her eyes was gone.
I took her to the office and moved a chair in front of Wolfe for her and went to my desk.
She exchanged greetings with Wolfe and said, 'I suppose you want money.'
'Money for what?' Wolfe asked.
'For finding my brother Carlo. You didn’t find him. Neither did the police. Some boys found him. I won’t pay you any money.'
'You might.' Wolfe sighed. 'I hadn’t thought of that, Miss Maffei. I’m sorry you suggested it. It arouses me to sordid considerations. But for the moment let us forget it; you owe me nothing. Forget it. But let me ask you-I am sorry if it is painful, but it is necessary-you saw your brother’s body?'
Her eyes were dull on him, but I saw that I had been wrong: the life in them was not gone, it had merely sunk within, waiting back there as if in ambush. She said quietly, 'I saw him.'
'You saw perhaps the hole in his back. The hole made by the knife of the man who killed him.'
'I saw it.'
'Good. And if there was a chance of my discovering the man who used that knife and bringing him to punishment, and needed your help, would you help me?'
In the dull eyes a gleam came and went. Maria Maffei said, 'I would pay you money for that, Mr. Wolfe.'
'I suspect you would. But we shall forget that for the present. It is another kind of assistance I require. Since you are intelligent enough to make reasonable assumptions, and therefore to be made uncomfortable when only reasonable ones are available, I had better explain to you. The man who murdered your brother is sought by me, and by others, for another act he committed. An act more sensational and not less deplorable. I know who he is, but your help is needed-'
'You know? Tell me!' Maria Maffei had jerked forward in her chair, and this time the gleam in her eyes stayed.
Wolfe wiggled a finger at her. 'Easy, Miss Maffei. I am afraid you must delegate your vengeance. Remember that those of us who are both civilized and prudent commit our murders only under the complicated rules which permit us to avoid personal responsibility. Let us get on. You can help. You must trust me. Your friend Fanny’s husband, Mr. Durkin, will tell you that I am to be trusted; besides, he will also help. I wish to speak of Miss Anna Fiore, the girl who works at the rooming house where your brother lived. You know her?'
'Of course I know her.'
Th 'Does she like you and trust you?'
'I don’t know. She is a girl who hides her flowers.'
'If any? A tender way of putting it; thank you. Could you go in my automobile this evening, with a driver, and persuade Miss Fiore to take a long ride with you; give her a good excuse, so she would go willingly?'
