"Nothing seems to have been used for some time." They descended the stairs again.
"You say you saw the two men enter this house, sir ?" the policeman remarked doubtfully.
"I did," Tavernake declared.

"There is no doubt about it." "The back entrances are all properly locked," the policeman pointed out.
"None of the windows by which any one could escape have been opened.
We've been into every room.

There's no one in the house now, sir, is there ?" "There doesn't seem to be," Tavernake admitted.
The policeman looked him over once more; Tavernake certainly had not the appearance of one attempting a hoax.
"I am afraid there is nothing more we can do, sir," the man said civilly.

"You had better give me your name and address." "Can't we go over the place once more ?" Tavernake suggested.

"I tell you I saw them come in." "I have my beat outside to look after, sir," the constable answered.
