Door To Door
“There.” Catherine told Art with a note of satisfaction in her voice. “That should keep you immobile and quiet until morning.” Securely bound and gagged, the travelling salesman blinked up at the tall woman uncomprehendingly. “Don’t look so confused, honey,” Catherine told her captive with a mysterious smile, “you can tell me who you really are while I feed you breakfast in the morning. Until then, try to get some sleep.” She swept away with rustle of her silk dress, then paused at the door of the sparsely furnished room, her smile taking on a darker look. "After all - you'll probably need it." Then she was gone.
Art stared after her, suddenly mmmmphing desperately. Who was she? What did she want with him? All he did was sell kitchen appliances door to door… What was going on??
