Read it through once

About four o'clock Esther saw Mrs. Barfield, Miss Mary, and Peggy walk across the yard towards the garden, and as Esther had to go soon after to the wood-shed she saw Peggy slip out of the garden by a bottom gate and make her way through the evergreens. Esther hastened back to the kitchen and stood waiting for the bell to ring. She had not to wait long; the bell tinkled, but so faintly that Esther said, "She only just touched it; it is a signal; he was on the look-out for it; she did not want anyone else to hear."
