only one glass of claret at luncheon, and I am perfectly healthy in body
and mind. How could I see such a thing if it was not there?"

"It was there," he declared.

"Do you really think so? A green--bright green mouse?"

"Haven't a doubt of it," he assured her; "saw one myself the other day."

"Where?"

"On the floor--" he made a vague gesture. "There's probably a crack
between your studio and my wall, and the little rascal crept into your
place."

She stood looking at him uncertainly: "Are there really such things as
green mice?"

"Well," he explained, "I fancy this one was originally white. Somebody
probably dyed it green."

"But who on earth would be silly enough to do such a thing?"

His ears grew red--he felt them doing it.

After a moment she said: "I am glad you told me that you, too, saw this
unspeakable mouse. I have decided to write to the owners of the house and
request an immediate investigation. Would--would it be too much to ask
you to write also?"
