 "One of the greatest authorities on poisons living," whispered Lauriston to Purdie, while Dr. Sperling-Lawson was taking the oath and answering the formal questions. "He's principal pathologist at that hospital they're talking about, and he constantly figures in cases of this sort. He's employed by the Home Office too—it was he who gave such important evidence in that Barnsbury murder case not so long since—don't you remember it?"

Purdie did remember, and he looked at the famous expert with great interest. There was, however, nothing at all remarkable about Dr. Sperling-Lawson's appearance—he was a quiet, self-possessed, plain-faced gentleman who might have been a barrister or a banker for all that any one could tell to the contrary. He gave his evidence in a matter-of-fact tone—strongly in contrast to Dr. Mirandolet's somewhat excited answers—but Purdie noticed that the people in court listened eagerly for every word.

He happened to be at the hospital, said Dr. Sperling-Lawson, when the man Parslett was brought in, and he saw him die. He fully agreed with Dr. Mirandolet that it was impossible to do anything to save the man's life when he was brought to the hospital, and he was quite prepared to say that the impossibility had existed from the moment in which Gardiner had seen Parslett collapse. In other words, when Parslett did collapse, death was on him.

"And—the cause of death?" asked the Coroner.

"Heart failure," replied the witness.

"Resulting from—what?" continued the Coroner.
