"'We have been to your residence,' said the first, 'and not being so fortunate as to find you there, and being informed that you were probably walking in this direction, we followed, in the hope of overtaking you. Will you please to enter the carriage?'

"The manner of both was imperious, and they both moved, as these words were spoken, so as to place me between themselves and the carriage door. They were armed. I was not.

"'Gentlemen,' said I, 'pardon me; but I usually inquire who does me the honour to seek my assistance, and what is the nature of the case to which I am summoned.'

"The reply to this was made by him who had spoken second. 'Doctor, your clients are people of condition. As to the nature of the case, our confidence in your skill assures us that you will ascertain it for yourself better than we can describe it. Enough. Will you please to enter the carriage?'

"I could do nothing but comply, and I entered it in silence. They both entered after me--the last springing in, after putting up the steps. The carriage turned about, and drove on at its former speed.

"I repeat this conversation exactly as it occurred. I have no doubt that it is, word for word, the same. I describe everything exactly as it took place, constraining my mind not to wander from the task.

"The carriage left the streets behind, passed the North Barrier, and emerged upon the country road. At two-thirds of a league from the Barrier--I did not estimate the distance at that time, but afterwards when I traversed it--it struck out of the main avenue, and presently stopped at a solitary house, We all three alighted, and walked, by a damp soft footpath in a garden where a neglected fountain had overflowed, to the door of the house. It was not opened immediately, in answer to the ringing of the bell, and one of my two conductors struck the man who opened it, with his heavy riding glove, across the face.

"There was nothing in this action to attract my particular attention, for I had seen common people struck more commonly than dogs. But, the other of the two, being angry likewise, struck the man in like manner with his arm; the look and bearing of the brothers were then so exactly alike, that I then first perceived them to be twin brothers.

"From the time of our alighting at the outer gate (which we found locked, and which one of the brothers had opened to admit us, and had relocked), I had heard cries proceeding from an upper chamber. I was conducted to this chamber straight, the cries growing louder as we ascended the stairs, and I found a patient in a high fever of the brain, lying on a bed.
