The story

Julian Maddox built Linnet, an artificial-intelligence companion that forty million people talk to. On a night when snow off Lake Ontario has shut every road, he is found dead in a hall of his own data centre. At eight that morning he was due to tell the public something he had kept from it. The building runs itself and keeps a record of everything it does. The last version of his speech is in a satellite overhead, and only one key opens it.
