The Duke of Battersea spread out a large sheet of paper upon the table before him, made a few notes, re-arranged certain details, was satisfied with his plan, and next, without looking up, stretched forth his hand to touch the electric bell. He was old and some of his movements uncertain. His finger had the misfortune to find not the electric bell but the ink-pot, into which it deeply plunged. A lesser man would have been disturbed at the accident, and a coarser one might have been moved to suck the injured limb. The Duke of Battersea showed no such weakness. He looked up, rubbed his finger on the blotting-pad, made sure of the electric bell, and when it was answered, said in a low voice: "Mr. Befan." The servant disappeared, and came back in half an hour with the message: "Mr. Bevan is not at the Agency, your grace; he is watching the Hampton divorce case, your grace. The Agency says, your grace, will you have Penderton?" "Certainly not," said the Duke of Battersea, still intent upon the paper before him. "Find out when he will be back." In a quarter of an hour he was told that the detective was expected home from Hertfordshire at half-past twelve that night. The duke looked at his watch, compared it with a fine specimen of Toledo clockwork set in a German monstrance upon the mantelpiece, and saw that he had an hour to wait. He made a motion with his hand and was left alone. He was determined to see Bevan and to see him that night, but it was nearly one in the morning before the door opened and the detective appeared. The detective was a short gentlemanly man with a hare lip and a malformation of the forehead which raised one eyebrow considerably above the other. He did not limp, but when he walked the emphasis was upon the right leg. His ears which were large and prominent did much to counter-balance the pleasing intelligence of his expression. He was not a man whom one would at the first sight, nor at the second, have chosen for the unravelling of difficult problems, but the Duke of Battersea knew far too much of the world to judge by any other standard than that of performance and of practice. And Mr. Bevan had not failed him on two recent occasions when rapid execution had been essential, as it was essential now. He wasted no words. He described who had to be watched and what evidence if possible had to be gathered. He gave the address in Bruton Street, and as the detective stood respectfully at the door, he named a hundred pounds. "It's worth a hundred and fifty, your grace," said Mr. Bevan, as he repeated the conditions which were laid down to him. "Sefen and sixpence," said the Duke with a gentle smile, "if what I have told you already was all indeed"--and having said that he gave time for it to soak in. Mr. Bevan changed his hat from one hand to the other, then held it in both hands and said he was sure he didn't mean to say more than one should say, and he would certainly leave it to the Duke, who nodded and answered him:
