There was no longer anything to keep her at the cottage. She spent an hour obsessionally cleaning and tidying rooms which no one would enter, probably for weeks. She watered the mug of cowslips on the sitting-room table. In another three days they would be dead and no one would notice, but she couldn't bear to throw out the still living flowers. She went out to the shed and contemplated the bottle of sour milk and the beef stew. Her first impulse was to take both and empty them down the lavatory. But they were part of the evidence. She wouldn't need that evidence again, but ought it to be completely destroyed? She recalled Bernie's reiterated admonition: 'Never destroy the evidence.' The Super had been full of cautionary tales to emphasize the importance of that maxim..In the end she decided to photograph the exhibits, setting them up on the kitchen table and paying great attention to exposure and light. It seemed a fruitless, somewhat ridiculous, exercise and she was glad when the job was done and the unsavoury contents of bottle and pan could be disposed of. Afterwards she carefully washed them both and left them in the kitchen.

Last of all she packed her bag and stowed her gear in the Mini together with Mark's jerseys and books. Folding the thick wool, she thought of Dr Gladwin sitting in his back garden, his shrunken veins indifferent to the sun. He would find the jerseys useful, but she couldn't take them to him. That kind of gesture might have been accepted from Mark, but not from her.

She locked the door and left the key under a stone. She couldn't face Miss Markland again and had no wish to hand it back to any other member of the family. She would wait until she got to London, then send a brief note to Miss Markland thanking her for her kindness and explaining where the key could be found. She walked for the last time round the garden. She wasn't sure what impulse led her to the well but she came up to it with a shock of surprise. The soil around the rim had been cleared and dug and had been planted with a circle of pansies, daisies and small clumps of alyssum and lobelia, each plant looking well established in its hollow ring of watered earth. It was a bright oasis of colour among the encroaching weeds. The effect was pretty but ridiculous and disquietingly odd. Thus strangely celebrated, the well itself looked obscene, a wooden breast topped by a monstrous nipple. How could she have seen the well cover as a harmless and slightly elegant folly?

Cordelia was torn between pity and revulsion. This must be the work of Miss Markland. The well, which for years had been to her an object of horror, remorse and reluctant fascinadon, was now to be tended as a shrine. It was ludicrous and pitiable and Cordelia wished that she hadn't seen it. She was suddenly terrified of meeting Miss Markland, of seeing the incipient madness in her eyes. She almost ran out of the garden, pulled the gate shut against the weight of the weeds and drove finally away from the cottage without a backward glance. The case of Mark Callender was finished.

chapter seven

Next morning she went to the Kingly Street office promptly at nine o'clock. The unnaturally hot weather had broken at last and when she opened the window, a keen breeze shifted the layers of dust on desk and filing cabinet. There was only one letter. This was in a long stiff envelope and was headed with the name and address of Ronald Callender's solicitors. It was very brief.

'Dear Madam, I enclose a cheque for £30.00 being expenses due to you in respect of the investigation which you carried out at the request of the late Sir Ronald Callender into the death of his son Mark Callender. If you agree this sum, I would be grateful if you would sign and return the attached receipt.'

Well, as Miss Learning had said, it would at least pay part of the fine. She had sufficient money to keep the Agency going for another month. If there were no further cases by that time, there was always Miss Feakins and another temporary job. Cordelia thought of the Feakins Secretarial Agency without enthusiasm. Miss Feakins operated, and that was the appropriate word, from a small office as squalid as Cordelia's own, but which had a desperate gaiety imposed upon it in the form of multi-coloured walls, paper flowers in a variety of urn-like containers, china ornaments and a poster. The poster had always fascinated Cordelia. A curvaceous blonde, clad in brief hot pants and laughing hysterically, was leap-frogging over her typewriter, a feat she managed to perform with a maximum of exposure while clutching a fistful of five pound notes in each hand. The caption read: 'Be a Girl Friday and join the fun people. All the best Crusoes are on our books.'

Beneath this poster Miss Feakins, emaciated, indefatigably cheerful and tinsled like a Christmas tree, interviewed a dispirited trail of the old, the ugly and the virtually unemployable. Her milch cows seldom escaped into permanent employment. Miss Feakins would warn against the unspecified dangers of accepting a permanent job much as Victorian mothers warned against sex. But Cordelia liked her. Miss Feakins would welcome her back, her defection to Bernie forgiven, and there would be another of those furtive telephone conversations with the fortunate Crusoe, made with one bright eye on Cordelia, a brothel madam recommending her latest recruit to one of her fussier customers. 'Most superior girl – well educated – you'll like her – and a worker!' The emphasis of amazed wonder on the last word was justified. Few of Miss Feakins' temporaries, beguiled by advertisements, seriously expected to have to work. There were other and more efficient agencies but only one Miss Feakins. Bound by pity and an eccentric loyalty, Cordelia had little hope of escaping that glittering eye. A series of temporary jobs with Miss Feakins' Crusoes might, indeed, be all that was left to her. Didn't a conviction for illegal possession of a weapon under Section I of the Firearms Act 1968 count as a criminal record, barring one for life from socially responsible and safe jobs in the civil service and local government?

She settled down at the typewriter, with the yellow telephone directory to hand, to finish sending out the circular letter to the last twenty solicitors on the list. The letter itself embarrassed and depressed her. It had been concocted by Bernie after a dozen preliminary drafts and, at the time, it hadn't seemed too unreasonable. But his death and the Callender case had altered everything. The pompous phrases about a comprehensive professional service, immediate attendance in any part of the country, discreet and experienced operators and moderate fees, struck her as ridiculously, even dangerously, pretentious. Wasn't there something about false representation in the Trades Description Act? But the promise of moderate fees and absolute discretion was valid enough. It was a pity, she thought drily, that she couldn't get a reference from Miss Learning. Alibis arranged; inquests attended; murders efficiendy concealed; perjury at our own special rates.

The raucous burr of the telephone startled her. The office was so quiet and still that she had taken it for granted that no one would call. She stared at the instrument for several seconds, wide-eyed and suddenly afraid, before stretching out her hand.

The voice was calm and assured, polite but in no way deferential. It uttered no threat, yet to Cordelia, every word was explicit with menace.

'Miss Cordelia Gray? This is New Scotland Yard. We wondered whether you would be back at your office yet. Could you please make it convenient to call here sometime later today? Chief Superintendent Dalgliesh would like to see you.'
