You have a point here, lookout.
Will you please turn to the Ground Floor Plan, depicting the rooms at the rear of WHF, kindly put up by Hartley.
In the Laundryroom (back-kitchen or 'den''), opposite the open back door, where it may be that Sheila is supine, you will notice thare is another exterior door(allegedly unused). In the event of this door having been breached by TFOfficer Woodcock (with his sledge hammer), then the early morning light flooding in from that eastern doorway, is likely to produce the illuminated situation in the mystery photograph. I.e. the floor area, beyond the settle, will understandably be in darkness. Does this make sense as to why the form! Is difficult to
Distinguish?
