From above their heads, a full-length portrait of the Queen stared unsmilingly across the room at window draperies, now drawn, of rich gold brocade. At the far end, festooned lights on a decorated Christmas tree flashed on and off. The buzz of conversation lessened perceptibly as the Prime Minister and his wife entered, Margaret Howden in a ball gown of pale mauve lace, above the gown her shoulders bare.

Still preceding, the naval lieutenant led the way directly to a point near a blazing log fire where the Governor General had been receiving. The aide announced: 'The Prime Minister and Mrs Howden.'

His Excellency, the Right Honourable Air Marshal Sheldon Griffiths, VC, DFC, RCAF (retired). Her Majesty's Governor General in the Dominion of Canada, extended his hand. 'Good evening. Prime Minister.' Then, inclining his head courteously, 'Margaret.'

Margaret Howden curtsied expertly, her smile including Natalie Griffiths at her husband's side.

'Good evening. Your Excellency,' James Howden said. 'You're looking extremely well.'

The Governor General, silver-haired, ruddy, and militarily erect despite his years, was wearing faultless evening dress with a long impressive row of medals and decorations. He leaned forward confidentially. 'I feel as if my damn tailplane's burning up.' Gesturing to the fireplace. 'Now you're here, let's move away from this inferno.'

Together the four strolled through the room, the Governor General a courteous, friendly host.

'I saw your new Karsh portrait,' he told Melissa Tayne, serene and gracious wife of Dr Borden Tayne, the Health and Welfare Minister. 'It's very beautiful and almost does you justice.' Her husband, alongside, flushed with pleasure.

Next to them Daisy Cawston, lumpish, motherly, and not caring, burbled, 'I've been trying to persuade my husband to sit for Karsh, Your Excellency, at least while Stuart has some hair left.' Beside her, Stuart Cawston, Finance Minister, and known to friends and adversaries as 'Smiling Stu', grinned good-naturedly.
