They entered the big stone mansion – official residence of Prime Minister for his term of office – by the awning-shielded main front door. Inside, Yarrow, the steward, vast them and took their coats. He announced, 'The American Ambassador has been trying to reach you, sir. The embassy called twice and stated the matter was urgent.'

James Howden nodded. Probably Washington had learned of the press leak too. If so, it would make Arthur Lexington's assignment that much easier. 'Wait for five minutes,' he instructed, 'then let the switchboard know that I'm home.'

'We'll have coffee in the drawing-room, Mr Yarrow,' Margaret said. 'And some sandwiches, please, for Mr Howden; he missed the buffet.' She stopped in the main-hall powder-room to arrange her hair.

James Howden had gone ahead, through the series of hallways to the third hall, with its big french doors overlooking the river and the Gatineau Hills beyond. It was a sight which always enraptured him and even at night, oriented by distant pin-point lights, he could visualize it: the wide wind-flecked Ottawa River; the same river which the adventurer Etienne Brule had navigated three centuries and a half before; and afterwards Champlain; and later the missionaries and traders, plying their legendary route westward to the Great Lakes and the fur-rich North. And beyond the river lay the distant Quebec shoreline, storied and historic, witness to many changes: much that had come, and much that would one day end.
