I have listened - twice - to this entire audiobook written by Walter Besant, brilliantly and dryly read by Ruth Golding - all eight hours of it - sometimes fully awake and sometimes properly asleep.
Take my recommendation: If you cannot sleep, have an enquiring mind and an inherent interest in history - particularly of London - then you will learn to love this, even when you are unconscious.
I almost recommended that it should be played to patients in a coma, but I think that could constitute torture in some cases.
I just cannot get my head around how some old academics could fill their own with so many facts and dates, and how learning and teaching has been so degraded since Walter Besant filled his own to overflowing.
What gifts we have been given.
Take your time.
