Locked Underground Stations
Secured tube stations throughout the London Underground network, locked by military order to protect Goodge Street fortress. Evans cites their locked status to block Jamie's overhead interception plan, warning that leaving traps the group outside with no way back amid Yeti patrols and Intelligence webs. Colonel Lethbridge-Stewart weighs the risk but splits forces anyway, Jamie skeptical of Evans' emphasis on the obstacle.
