e mitten, and I think it belongs to Don. No, don't ask
questions. I haven't time to answer them. Just find out from Don's
nurse what his mittens were like and then come straight over here, and
be sure not to say anything to your mother or your uncle, for I may be
all wrong."

She hung up the receiver before Chuck could reply and hurried back to
the snuggery. Janet was still looking out of the window as though she
feared the mitten might fly away if she took her eyes from it.

They waited until the door bell announced Chuck's arrival. Phyllis
flew down the stairs to meet him.

"Here," he said, by way of greeting and he handed her a white mitten.

Phyllis took it eagerly; it had a blue border, and it was handmade
after a pattern of long ago.

"Nannie always makes them," Chuck explained. "Where's the one you

Janet gave the glasses to Chuck as soon as he entered the snuggery and

some one rang the bell when the caretaker was out, Miss Pringle would
have to come to the door. That would leave the coast clear for you."

"Go on," Chuck prompted.

"There's nothing else," Phyllis answered. "We will just have to wait
until the caretaker goes out."

Chuck groaned at the thought of time wasted.

"When's that likely to be?" he demanded.

"About sunset. He takes care of some of the furnaces in the
neighborhood, so he'll be gone for quite a while," Phyllis told him.

"I'll go and watch at the corner," Chuck decided.

"What are you going to do if you find the mitten is Don's?" the
practical Janet asked, and Phyllis and Chuck looked at each other.

"Notify the police," Chuck said at las
