When Dora is told that miners at the local coal pit are on strike and that they have left their pit ponies below, she decides to interfere despite being warned not to intensify a delicate situation, but Dora can't stand by and do nothing.
Dora thought Arthur Wimble was a nice old man, and he is, in spite of the problem he creates. Steve has an even greater problem to face - and a debt to pay.
