Read it through once

"I lived with her more than thirty years; I brought up all the children. I entered her service as nurse, and when the children grew up I was given the management of everything. For the last fifteen years my mistress was a confirmed invalid. She entrusted everything to me. Oftentimes she took my hand and said, 'You are a good creature, Holmes, you mustn't think of leaving me; how should I get on without you?' But when she died they had to part with me; they said they were very sorry, and wouldn't have thought of doing so, only they were afraid I was getting too old for the work. I daresay I was wrong to stop so long in one situation. I shouldn't have done so, but she always used to say, 'You mustn't leave us; we never shall be able to get on without you.'"
