"Finally, with a desperate effort, she freed herself, and ran for her life across the golf links, expecting every minute to be shot down with a revolver bullet. She fell twice-tripping over the heather, but eventually regained the road to the station and realised that she was not being pursued.

"That is the story that Doris Evans tells-and from which she has never varied. She strenuously denies that she ever struck at him with a hat pin in self defence-a natural enough thing to do under the circumstances, though-and one which may well be the truth. In support of her story a revolver has been found in the furze bushes near where the body is lying. It had not been fired.

"Doris Evans has been sent for trial, but the mystery still remains a mystery. If her story is to be believed, who was it who stabbed Captain Sessle? The other woman, the tall woman in brown whose appearance so upset him? So far no one has explained her connection with the case. She appears out of space suddenly on the footpath across the links, she disappears along the slip, and no one ever hears of her again. Who was she? A local resident? A visitor from London? If so, did she come by car or train? There is nothing remarkable about her except her height, no one seems to be able to describe her appearance. She could not have been Doris Evans for Doris Evans is small and fair, and moreover was only just then arriving at the station."

"The wife?" suggested Tuppence. "What about the wife?"

"A very natural suggestion. But Mrs. Sessle is also a small woman, and besides Mr. Hollaby knows her well by sight, and there seems no doubt that she was really away from home. One further development has come to light. The Porcupine Assurance Co. is in liquidation. The accounts reveal the most daring misappropriation of funds. The reasons for Captain Sessle's wild words to Doris Evans are now quite apparent. For some years past, he must have been systematically embezzling money. Neither Mr. Hollaby, nor his son, had any idea of what was going on. They are practically ruined.

"The case stands like this. Captain Sessle was on the verge of discovery and ruin. Suicide would be a natural solution, but the nature of the wound rules that theory out. Who killed him? Was it Doris Evans? Was it the mysterious woman in brown?"

Tommy paused, took a sip of milk, made a wry face, and bit cautiously at the cheese cake.
