Tactful, of course, and calculated to put the guest completely at his ease.

'I remember Oliver,' said Exhibit B, looking at me in much the same way as the Bosher Street beak had looked at Sippy before putting on the black cap. 'Nasty little boy! He teased my cat.'

'Aunt Jane's memory is wonderful, considering that she will be eighty-seven next birthday,' whispered Mrs Pringle with mournful pride.

'What did you say?' asked the Exhibit suspiciously.

'I said your memory was wonderful.'

'Ah!' The dear old creature gave me another glare. I could see that no beautiful friendship was to be looked for by Bertram in this quarter. 'He chased my Tibby all over the garden, shooting arrows at her from a bow.'

At this moment a cat strolled out from under the sofa and made for me with its tail up. Cats always do take to me, which made it all the sadder that I should be saddled with Sippy's criminal record. I stooped to tickle it under the ear, such being my invariable policy, and the Exhibit uttered a piercing cry.

'Stop him! Stop him!'

She leaped forward, moving uncommonly well for one of her years, and having scooped up the cat, stood eyeing me with bitter defiance, as if daring me to start anything. Most unpleasant.

'I like cats,' I said feebly.
