失踪的中卫(19)

“We can follow him to-morrow.”

“Can we? It is not so easy as you seem to think. You are not familiar with Cambridgeshire scenery, are you? It does not lend itself to concealment. All this country that I passed over to-night is as flat and clean as the palm of your hand, and the man we are following is no fool, as he very clearly showed to-night. I have wired to Overton to let us know any fresh London developments at this address, and in the meantime we can only concentrate our attention upon Dr. Armstrong, whose name the obliging young lady at the office allowed me to read upon the counterfoil of Staunton's urgent message. He knows where the young man is—to that I'll swear—and if he knows, then it must be our own fault if we cannot manage to know also. At present it must be admitted that the odd trick is in his possession, and, as you are aware, Watson, it is not my habit to leave the game in that condition.”

And yet the next day brought us no nearer to the solution of the mystery. A note was handed in after breakfast, which Holmes passed across to me with a smile.

Sir [it ran]:

I can assure you that you are wasting your time in dogging my movements. I have, as you discovered last night, a window at the back of my brougham, and if you desire a twenty-mile ride which will lead you to the spot from which you started, you have only to follow me. Meanwhile, I can inform you that no spying upon me can in any way help Mr. Godfrey Staunton, and I am convinced that the best service you can do to that gentleman is to return at once to London and to report to your employer that you are unable to trace him. Your time in Cambridge will certainly be wasted.

Yours faithfully,

Leslie Armstrong.
