Daylight Saving Case

Daylight savings time hits Seattle and several blocks go dark around a bank in down town. In less than two hours all the lights come on. The bank officials were locked out of their building. With the lights back on, they find the vaults open and $50 million in cash has walked off. The total weight is about half a ton.
The bank officials, police, and firemen were around the building when the lights were out. No one could get in or out of the building. Patrolman Rage in her car with a rookie circled the building several various times during the blackout. She has some ideas which she shares with robbery. Then her friend patrolman Jones go sightseeing on the famous Seattle underground tours.
Why is there an underground tour? After the Seattle fire of 1889, the city fathers raised some of the streets in Seattle from 12 to 30 feet to prevent flooding. It also let the toilets flush at high tide. They built walls to hold the dirt and paved over them. The city only owned the streets and could not dump dirt on the land. With some stores already rebuilt, their customers where climbing ladders down from the streets to the main entrances to the stores.
