The Chalk Circle Man by Fred Vargas

to fail. But as for whether the dead woman was put into a circle that had already been drawn or not, the lab people say it’s impossible to tell. Maybe yes, maybe no. Does that sound like forensic science to you? And the corpse hasn’t been much help, either: this is the corpse of a woman who led a totally uneventful existence, nothing odd at all, no complicated love life, no skeletons in the family cupboard, no problems with money, no secret vices. Nothing. Just balls of wool and more balls of wool, holidays in the Loire Valley, calf-length skirts, sensible shoes, a little diary that she wrote notes in, half a dozen packets of currant biscuits in her kitchen cupboard. In fact she wrote about that in her diary: “Can’t eat biscuits in the shop, if you drop crumbs the boss notices.” And so on and so forth. So you might say, well, what on earth was she doing out late at night? And the answer is she was coming back home after seeing her cousin, who works in the ticket office at the Luxembourg metro station. The victim often used to go over there and sit alongside her in the booth, eating crisps, and knitting Inca-style gloves to sell in the wool shop. And then she would go back home, on foot, probably along the rue Pierre-et-Marie Curie.’
    ‘Is the cousin her only family?’
    ‘Yes, and she’ll inherit the estate. But since it consists of the currant biscuits plus a tea caddy with a few banknotes in, I can’t see the cousin or her husband cutting Madeleine Châtelain’s throat for that.’
    ‘But if someone wanted to use a chalk circle, how would they have known where there was going to be one that night?’
    ‘That is indeed the question, my little ones. But we ought to be able to work it out.’
    Danglard got up carefully, to put Number Five, René, to bed.
    ‘For instance,’ he resumed, ‘take the commissaire ‘s new friend, Mathilde Forestier: it seems that she’s actually seen the chalk circle man. Adamsberg told me. Look, I’m managing to say his name again. Obviously the conference is doing me good.’
    ‘At the moment, I’d say it was a one-man conference,’ Édouard observed.
    ‘And this woman, who knows the chalk circle man, she worries me,’ Danglard added.
    ‘You said the other day,’ said the first-born girl of the second set of twins, ‘that she was beautiful and tragic and spoilt and hoarse-voiced, like some exotic Egyptian queen, but she didn’t worry you then.’
    ‘You didn’t think before you spoke, little girl. The other day, nobody had been killed. But now, I can just see her coming into the police station, on some damfool pretext, making a big fuss, getting to see Adamsberg. And then talking to him about this, that and the other, before getting round to telling him she knows this chalk circle man pretty well. Ten days before the murder – bit of a coincidence isn’t it?’
    ‘You mean she’d planned to kill Madeleine, and she came to see Adamsberg so that she’d be in the clear?’ asked Lisa. ‘Like that woman who killed her grandfather but came to see you a month before, to tell you she had a “presentiment”? Remember?’
    ‘You remember that dreadful woman? Not an Egyptian princess at all, and as slimy as a reptile. She nearly got away with it. It’s the classic trick of the murderer who telephones to say they’ve found a body, only more elaborate. So, well, yes. Mathilde Forestier turning up like that does make you think. I can just imagine what she’d say: “But commissaire , I’d hardly have come and told you I knew all about the chalk circle man if I was intending to use him to cover up a murder!” It’s a dangerous game, but it’s bold, and it could be just her style. Because she is a bold woman, you’ve probably gathered that.’
    ‘So did she have a motive for killing poor fat Madeleine?’
    ‘No,’ said Arlette. ‘This lady, Madeleine, must just have been unlucky, picked by chance to start a series, so they’d pin it on the circle maniac.
