her.
She smiled broadly. âI know. We must all seem rather peculiar to you. I want to tell you something.â
Looking at her I realized that there was something very ruthless about this young woman. I felt it had cost her a great effort to come to me, but that it was part of a course of action on which she was utterly determined. âBefore you do so,â I said gently, âmay I ask why you should have chosen me? There must surely be someone you know better in whom you can confide.â
âThatâs just it,â she said. âThey were all here. They are all concerned in this thing, and you are not.â
âThey werenât all here,â I pointed out. âWhy donât you go to Christine Derosse? She has just arrived and Iâm sure sheâs more able to cope with things than I am.â
She shook her head vigorously. âOh no! âshe said. âShe doesnât like me and I wouldnât trust her. Besides,it is not after all very much that I want to ask you. Just to look after something for me for a few days.â
âSomething?â
âWell, an envelope.â
âAn empty envelope?â
âOf course not, Mrs Gort.â She could smile charmingly when she liked. âIt has a ⦠paper in it.â
âA letter?â
âA sort of letter.â
âBut, my dear girl, why on earth donât you put it in your bank for safe keeping? Even with all the safe-blowing and bank raids weâre having nowadays, surely a bank is the safest place for a valuable document?â
âThere are two reasons, as a matter of fact. But the chief one is that I need this document here in the house.â
âThen hide it in your room.â
âI have. But I never feel itâs safe. My roomâs been searched twice.â
âYou may be surprised to know that my room has been searched, too.â
âSurprisedâ was mild. She positively goggled at me. âYours? But why?â
âI supposed that it was because I foolishly admitted keeping a diary.â
She stared at me, seeming to consider this. âWas your diary taken?â
âNo. But it may have been read. Iâve had a Yale lock put on the door now.â
âThen
do
take thisâif itâs only for tonight.â She opened her bag and was about to take out a thickly sealed envelope. But as she did so I was able to observe that her bag held two of these and they looked identical.
âWhy tonight?â I asked firmly.
âBecause ⦠Oh, I donât know. I have a feeling â¦â
âYou know, Miss Reid, what you are asking me is quiteimpossible. I couldnât look after a document the nature of which I donât know. And you admit that someone wants to get hold of it.â
She was evidently determined to try everything. Tears were in her large eyes. âI thought you would help me.â
âHow can I when I donât know what I am helping you to do? Letâs be frank and say what it
looks
like.â
âWhat does it look like?â
âBlackmail,â I said, and let the word hang in the air.
She grew neither indignant nor hysterical. âYou mean you think this document contains evidence against someone?â
âCould be,â I said relentlessly.
âPerhaps you think it contains evidence that Lydia Mallister was murdered? âThere was a strange, rather dangerous calm in her voice now.
âLook at it from my point of view. Remember what I have seen and heard in this house about Lydia Mallisterâs death. Itâs not an unreasonable conclusion to draw, is it?â
âMrs Gort, I swear it isnât that. You must believe me. The envelope I ask you to keep contains a document, yes, but it contains no evidence that Lydia Mallister was murdered.â
âYou promise that?â
âIâll swear to it. Oh, please keep this for me.â
For a moment I hesitated, then fortunately
