“If, in spite of my warnings, you make up your mind to go through with it, you will find everything arranged.  You have lived for two years with Miss Dufferin, The Parsonage, Llanelly, and Mrs. Vandemeyer can apply to her for a reference.

“May I be permitted a word or two of advice?  Stick as near to the truth as possible—­it minimizes the danger of ‘slips.’  I suggest that you should represent yourself to be what you are, a former V.A.D., who has chosen domestic service as a profession.  There are many such at the present time.  That explains away any incongruities of voice or manner which otherwise might awaken suspicion.

“Whichever way you decide, good luck to you.  “Your sincere friend, “Mr. Carter.”

Tuppence’s spirits rose mercurially.  Mr. Carter’s warnings passed unheeded.  The young lady had far too much confidence in herself to pay any heed to them.

With some reluctance she abandoned the interesting part she had sketched out for herself.  Although she had no doubts of her own powers to sustain a role indefinitely, she had too much common sense not to recognize the force of Mr. Carter’s arguments.

There was still no word or message from Tommy, but the morning post brought a somewhat dirty postcard with the words:  “It’s O.K.” scrawled upon it.

At ten-thirty Tuppence surveyed with pride a slightly battered tin trunk containing her new possessions.  It was artistically corded.  It was with a slight blush that she rang the bell and ordered it to be placed in a taxi.  She drove to Paddington, and left the box in the cloak room.  She then repaired with a handbag to the fastnesses of the ladies’ waiting-room.  Ten minutes later a metamorphosed Tuppence walked demurely out of the station and entered a bus.

It was a few minutes past eleven when Tuppence again entered the hall of South Audley Mansions.  Albert was on the look-out, attending to his duties in a somewhat desultory fashion.  He did not immediately recognize Tuppence.  When he did, his admiration was unbounded.

“Blest if I’d have known you!  That rig-out’s top-hole.”

“Glad you like it, Albert,” replied Tuppence modestly.  “By the way, am I your cousin, or am I not?”

“Your voice too,” cried the delighted boy.  “It’s as English as anything!  No, I said as a friend of mine knew a young gal.  Annie wasn’t best pleased.  She’s stopped on till to-day—­to oblige, she said, but really it’s so as to put you against the place.”

“Nice girl,” said Tuppence.

Albert suspected no irony.

“She’s style about her, and keeps her silver a treat—­but, my word, ain’t she got a temper.  Are you going up now, miss?  Step inside the lift.  No. 20 did you say?” And he winked.

Tuppence quelled him with a stern glance, and stepped inside.

As she rang the bell of No. 20 she was conscious of Albert’s eyes slowly descending beneath the level of the floor.
