‘If I were only sure,’ she repeated to herself. ‘If I could only be sure.’

In vain she told herself that anything compromising would have been destroyed ages ago. Against that she argued that men do sometimes keep the most damning piece of evidence through an exaggerated sentimentality.

In the end Alix succumbed. Her cheeks burning with the shame of her action, she hunted breathlessly through packets of letters and documents, turned out the drawers, even went through the pockets of her husband’s clothes. Only two drawers eluded her; the lower drawer of the chest of drawers and the small right-hand drawer of the writing-desk were both locked. But Alix was by now lost to all shame. In one of these drawers she was convinced that she would find evidence of this imaginary woman of the past who obsessed her.

She remembered that Gerald had left his keys lying carelessly on the sideboard downstairs. She fetched them and tried them one by one. The third key fitted the writing-table drawer. Alix pulled it open eagerly. There was a cheque-book and a wallet well stuffed with notes, and at the back of the drawer a packet of letters tied up with a piece of tape.

Her breath coming unevenly, Alix untied the tape. Then a deep burning blush overspread her face, and she dropped the letters back into the drawer, closing and relocking it. For the letters were her own, written to Gerald Martin before she married him.

She turned now to the chest of drawers, more with a wish to feel that she had left nothing undone than from any expectation of finding what she sought.

To her annoyance none of the keys on Gerald’s bunch fitted the drawer in question. Not to be defeated, Alix went into the other rooms and brought back a selection of keys with her. To her satisfaction the key of the spare room wardrobe also fitted the chest of drawers. She unlocked the drawer and pulled it open. But there was nothing in it but a roll of newspaper clippings already dirty and discoloured with age.

Alix breathed a sigh of relief. Nevertheless, she glanced at the clippings, curious to know what subject had interested Gerald so much that he had taken the trouble to keep the dusty roll. They were nearly all American papers, dated some seven years ago, and dealing with the trial of the notorious swindler and bigamist, Charles Lemaitre. Lemaitre had been suspected of doing away with his women victims. A skeleton had been found beneath the floor of one of the houses he had rented, and most of the women he had ‘married’ had never been heard of again.

He had defended himself from the charges with consummate skill, aided by some of the best legal talent in the United States. The Scottish verdict of ‘Not Proven’ might perhaps have stated the case best. In its absence, he was found Not Guilty on the capital charge, though sentenced to a long term of imprisonment on the other charges preferred against him.
