The Case with Nine Solutions · Chapter
VII: The Fly in the Amber explained
Sir Clinton Driffield and Inspector Flamborough visit Dr.
What happens
Sir Clinton Driffield and Inspector Flamborough visit Dr. Trevor Markfield at the Croft-Thornton Institute to seek his expertise in a poisoning case involving Mrs. Silverdale. Markfield initially suggests consulting his chief, Dr. Silverdale, but is shocked to learn that the victim is Yvonne Silverdale. He agrees to assist. During questioning, Markfield reveals his acquaintance with the Silverdales and his recent sighting of Dr. Silverdale with Avice Deepcar. The interview pivots when a distinctive cigarette-holder with a fly in amber is produced. Markfield hesitates to identify it, but the head mechanic Gilling confirms he made two such holders for Dr. Silverdale three months ago. Flamborough notes Markfield's evasiveness and later, with Sir Clinton, speculates that the mysterious 'Peeping Tom' might be a woman.
