While I was engaged in this occupation, I suddenly heard strange voices in the large workroom.

My curiosity was instantly excited.

I drew back the little shutter from the peephole in the wall, and looked through it.
I saw first my old enemy, Screw, with his villainous face much paler than usual; next, two respectably-dressed strangers whom he appeared to have brought into the room; and next to them Young File, addressing himself to the doctor.
"I beg your pardon, sir," said my friend, the workman-like footman; "but before these gentlemen say anything for themselves, I wish to explain, as they seem strangers to you, that I only let them in after I had heard them give the password.

My instructions are to let anybody in on our side of the door if they can give the password.

No offense, sir, but I want it to be understood that I have done my duty." "Quite right, my man," said the doctor, in his blandest manner.
