This book belonged to a library before but remained in a good condition - llustrated by Jael Lordan. >>> John, Mary, Fitch and Bertha meet a litltle man who emerges from the door at the base of a lamp-post. He tells them that he and his friends are in danger from 'the enemy' - a claim that is borne out when there is a mysterious explosion in the neighbourhood. The children readily agree to help, make elaborate plans and finally move into the sewers leading to the Thames where the enemy are marshalling their forces.
