She was destined for a rude awakening. As soon as Mrs Fergus and she reached Blackwaterfoot to catch the Machrie bus, the news burst upon them. There had been a hold-up at the post-office! A masked man had burst in upon the post-mistress and stolen the mail at the point of a gun. It had happened just as the post-mistress was sealing the mail-bags to send them off in the two o'clock bus to Brodick. The post-mistress had fainted dead away on the floor, and if a visitor hadn't happened to come in, she would have been on the floor yet.
