Lady Janet led the way into the library. She opened the door—started—and suddenly stepped aside, so as to leave the entrance free.

A man appeared in the open doorway.

He was not a gentleman; he was not a workman; he was not a servant. He was vilely dressed, in glossy black broadcloth. His frockcoat hung on him instead of fitting him. His waistcoat was too short and too tight over the chest. His trousers were a pair of shapeless black bags. His gloves were too large for him. His highly-polished boots creaked detestably whenever he moved. He had odiously watchful eyes—eyes that looked skilled in peeping through key-holes. His large ears, set forward like the ears of a monkey, pleaded guilty to meanly listening behind other people’s doors. His manner was quietly confidential when he spoke, impenetrably self-possessed when he was silent. A lurking air of secret service enveloped the fellow, like an atmosphere of his own, from head to foot. He looked all round the magnificent room without betraying either surprise or admiration. He closely investigated every person in it with one glance of his cunningly watchful eyes. Making his bow to Lady Janet, he silently showed her, as his introduction, the card that had summoned him. And then he stood at ease, self-revealed in his own sinister identity—a police officer in plain clothes.

Nobody spoke to him. Everybody shrank inwardly as if a reptile had crawled into the room.

He looked backward and forward, perfectly unembarrassed, between Julian and Horace.

“Is Mr. Julian Gray here?” he asked.

Julian led Grace to a seat. Her eyes were fixed on the man. She trembled—she whispered, “Who is he?” Julian spoke to the police officer without answering her.

“Wait there,” he said, pointing to a chair in the most distant corner of the room. “I will speak to you directly.”

The man advanced to the chair, marching to the discord of his creaking boots. He privately valued the carpet at so much a yard as he walked over it. He privately valued the chair at so much the dozen as he sat down on it. He was quite at his ease: it was no matter to him whether he waited and did nothing, or whether he pried into the private character of every one in the room, as long as he was paid for it.

Even Lady Janet’s resolution to act for herself was not proof against the appearance of the policeman in plain clothes. She left it to her nephew to take the lead. Julian glanced at Mercy before he stirred further in the matter. He alone knew that the end rested now not with him but with her.
