Of a sudden the man broke out into blasphemies and cataracts of incredulous words. There was something shocking about the dropping of his mask; it was like a man’s real face falling off.
“See here!” he cried in broad American, when he was breathless with cursing, “I may be an adventurer, but I guess you’re a murderess. Yes, gentlemen, here’s your death explained, and without any levitation. The poor girl is writing a will in my favour; her cursed sister comes in, struggles for the pen, drags her to the well, and throws her down before she can finish it. Sakes! I reckon we want the handcuffs after all.”
“As you have truly remarked,” replied Joan, with ugly calm, “your clerk is a very respectable young man, who knows the nature of an oath; and he will swear in any court that I was up in your office arranging some typewriting work for five minutes before and five minutes after my sister fell. Mr. Flambeau will tell you that he found me there.”
There was a silence.
“Why, then,” cried Flambeau, “Pauline was alone when she fell, and it was suicide!”
“She was alone when she fell,” said Father Brown, “but it was not suicide.”
“Then how did she die?” asked Flambeau impatiently.
“She was murdered.”
“But she was alone,” objected the detective.
“She was murdered when she was all alone,” answered the priest.
