“Ah! but we must not be precipitate,” said Mr. Murbles, rounding upon him. “To the lay mind, doubtless, the word ‘issue’ appears a simple one. But in law”—(Mr. Murbles, who up till this point had held the index-finger of the right hand poised against the ring-finger of the left, in recognition of the claims of the brothers and sisters of the half-blood, now placed his left palm upon the table and wagged his right index-finger admonishingly in Parker’s direction)—“in law the word may bear one of two, or indeed several, interpretations according to the nature of the document in which it occurs and the date of that document.”

“But in the new Act—” urged Lord Peter.

“I am not, particularly,” said Mr. Murbles, “a specialist in the law concerning property, and I should not like to give a decided opinion as to its interpretation, all the more as, up to the present, no case has come before the Courts bearing on the present issue—no pun intended, ha, ha, ha! But my immediate and entirely tentative opinion—which, however, I should advise you not to accept without the support of some weightier authority—would be, I think, that issue in this case means issue ad infinitum, and that therefore the great-nephews and great-nieces would be entitled to inherit.”

“Yes—the question is a complicated one—”

“What did I tell you?” groaned Peter. “I knew this simplifying Act would cause a shockin’ lot of muddle.”

“May I ask,” said Mr. Murbles, “exactly why you want to know all this?”

“Why, sir,” said Wimsey, taking from his pocket-book the genealogy of the Dawson family which he had received from the Rev. Hallelujah Dawson, “here is the point. We have always talked about Mary Whittaker as Agatha Dawson’s niece; she was always called so and she speaks of the old lady as her aunt. But if you look at this, you will see that actually she was no nearer to her than great-niece: she was the grand-daughter of Agatha’s sister Harriet.”

“Quite true,” said Mr. Murbles, “but still, she was apparently the nearest surviving relative, and since Agatha Dawson died in 1925, the money passed without any question to Mary Whittaker under the old Property Act. There’s no ambiguity there.”

“No,” said Wimsey, “none whatever, that’s the point. But—”
