The Time Mirror

A newly engaged couple receive an ornate antique mirror that, instead of ordinary reflections, shows the bride as a different woman from another era; that reflected figure exerts a psychic pull, causing the bride to lose control and begin to be drawn into the mirror. Her fiancé struggles to keep her and then seeks scientific help, linking the anomaly to experiments on preventing pilot blackouts and to extreme speeds in space, and they devise a plan to construct an insulated mirror device to retrieve her and halt the temporal transfer.
