Read it through once

Three days afterwards, between twelve and one, just the busiest time, when the bar was full of people, there came a cry of "Police!" An effort was made to hide the betting plant; a rush was made for the doors. It was all too late; the sergeant and a constable ordered that no one was to leave the house; other police were outside. The names and addresses of all present were taken down; search was made, and the packets of money and the betting books were discovered. Then they all had to go to Marlborough Street.
