There was a dead silence. They all looked at the picture. Peter was the first to speak. He said, “Well, it lets Bobby out,” and with that he went through to the hall and took the telephone down from its hook.
Lee got painfully to her feet. They were quite numb. Her mind felt like that too. If Mrs. Green was Ross’s wife, Aggie Crouch, then what was she doing here pretending to be Mrs. Green? And where was she now?
She heard Peter at the telephone, and then she heard the click as he put the receiver back. He came in and picked up the photograph. It had fallen into Lucy Craddock’s lap, where it lay in that proximity to the Craddock relations which the refinement of Miss Mary Craddock’s taste had proscribed. A portion of Aunt Sabina’s crinoline obscured the dustpan and brush. The head with its battered hat had come to rest on the proud shoulder of Uncle Henry Albert. He said,
“Lamb is coming round. Well, I suppose this lets us all out. Amazing-isn’t it?”
Lee said, “It doesn’t prove she did it.”
“It will make the police sit up and think a bit. And she’s rather given herself away by disappearing. Just a little bit too clever, that business of ringing up Scotland Yard saying she’d got some hush-hush evidence, and then working off the piece about being frightened of me, and of poor old Rush. The damnable thing is that it might have come off. Lee, do you realize how very easily it might have come off? By gum, she’s a clever woman! What was it Lucinda said-very versatile? I’ll say she is. She probably came down here in the first instance to spy out the land. Ross wouldn’t give her any more money, and she may have wanted a line on him for blackmail, or even for a divorce. I wonder if she bribed old Mother What’s-her-name to retire and let her in here as charwoman. Ross hadn’t seen her for twenty years by all accounts. Mrs. Green was an ironclad disguise, and she put on the port-wine mark just to make quite sure. I don’t suppose Ross ever really got a look at her. She had nothing to do with his flat, and it would be easy enough to keep out of his way. Even if he passed her on the stairs, she’d only got to go down on her knees and start dusting between the banisters or something like that. I shouldn’t think he ever saw her face, but he might have seen it a dozen times without recognizing her. He probably remembered her like this.” He reached over for the first photograph and gave a short laugh. “Tights, curves, eyes, teeth, hair-not much there that you would connect with Mrs. Green, is there? Well, there she was. And all the time someone was moving around from one lot of cheap lodgings to another, calling herself Rosalie La Fay, forwarding Aggie’s letters to old Prothero, and getting his answers back. I wonder who it was. Didn’t you say there was a sister?”
“Yes,” said Lucy Craddock in a flustered voice-“oh, yes, a sister-but I don’t remember her name.”
Peter nodded.
“Probably the sister then. Anyhow somebody she could trust to hold her tongue and do what she was told. Then Aggie gets her opportunity. She finds Ross’s key sticking in the door of his flat. She pinches it, and when Ross and Peterson are both out of the way for the day she goes in and has a good worry around. It was easy enough to dodge old Rush, because he’s got his settled times for everything, and she’d know what they were by then. Well, we know that Ross left his own bunch of keys lying about that day. That’s what he had the row with Rush about. He saw his papers had been meddled with and he accused Rush-‘Clean forgot himself Mr. Ross did,’ as the old boy put it to me. But it was Aggie. It must have been Aggie. And the first thing she saw when she opened that despatch-case was old Prothero’s letter urging Ross to make a will, and saying that the unsettled property amounted to a very considerable fortune and he ought to provide against any possibility of an intestacy. Mrs. Green mightn’t have made much of that letter, but you can bet your life that Aggie sucked it dry. If she was in any doubt she had only got to get the sister in Birmingham to go and ask the nearest solicitor. She could have copied the letter without names, or with different names, and have asked what the position of a widow would be if the husband died leaving a lot of unsettled property and no will. And I expect it was right there that she began to think of being Ross’s widow in desperate earnest. I don’t know how she brought it off all the same. She went home, and she went to bed drunk at half past nine. But I suppose she probably wasn’t really drunk at all, and allowing for that-”
Lee caught him suddenly by the arm.
“The Connells’ flat!” she said in a breathless voice.
All this time Lucy Craddock’s eyes had been round and fixed. They did not leave Peter’s face, but they did not really appear to be seeing him or anything else. She blinked rapidly now, and said in a small, obstinate voice,
“Oh, no, my dear, the Connells were away. And in any case-”
“Not the Connells,” said Lee-“their flat. Mrs. Green-she had their key. She said so when she was going off on the Tuesday night. She said she had just finished cleaning up after them, and Rush was furious because she didn’t give him the key before she went. You know she had one of her bad turns, but I suppose it was just acting really. I am sure she just went home and pretended to be drunk so that the other people in the house would leave her alone, but I think she slipped back here-Rush doesn’t lock up till eleven-and hid in the Connells’ flat. It-it’s just underneath Ross’s, and she would be able to listen and make sure that everything was quiet before she came out.”
“You think she shot Ross?” said Lucy Craddock in horrified accents.
“What do you think, Lucinda?” said Peter drily.
