Can't you prescribe complete solitude, as being absolutely essential for me?
Dick, I'm wretched! I don't care where I go; but I want to get away by myself." "Why, old man ?" "Because my wife still considers me insane." "Nonsense, Ron! And don't talk of being insane.

You were never that.
Some subtle malarial poison, we shall never know what, got into your blood, affected your brain, and you've had a bad time--a very bad time--of being completely off your balance; the violent stage being followed by loss of memory, and for a time, though mercifully you knew nothing about it, complete loss of sight.

But these things returned, one by one; and, as soon as you were ready for it, you awoke to consciousness, memory, and reason.

There is no possible fear of the return of any of the symptoms, unless you come again in contact with the poison; hardly likely, as it attacked you in Central Africa.

Of course, as I say, we shall never know precisely what the poison was." Then Ronnie spoke, suddenly.
