I sent him home in the car, with a bunch of hot-house roses for his wife, and he was quite overwhelmed.  As for me, I had a generous glow that was cheap at the price of a church carpet.  I received less gratification—­and less gratitude—­when I presented the new silver communion set to St. Barnabas.

I had a great many things to think about in those days.  I made out a list of questions and possible answers, but I seemed only to be working around in a circle.  I always ended where I began.  The list was something like this: 

Who had entered the house the night before the murder?

Thomas claimed it was Mr. Bailey, whom he had seen on the foot-path, and who owned the pearl cuff-link.

Why did Arnold Armstrong come back after he had left the house the night he was killed?

No answer.  Was it on the mission Louise had mentioned?

Who admitted him?

Gertrude said she had looked the east entry.  There was no key on the dead man or in the door.  He must have been admitted from within.

Who had been locked in the clothes chute?

Some one unfamiliar with the house, evidently.  Only two people missing from the household, Rosie and Gertrude.  Rosie had been at the lodge.  Therefore—­but was it Gertrude?  Might it not have been the mysterious intruder again?

Who had accosted Rosie on the drive?

Again—­perhaps the nightly visitor.  It seemed more likely some one who suspected a secret at the lodge.  Was Louise under surveillance?

Who had passed Louise on the circular staircase?

Could it have been Thomas?  The key to the east entry made this a possibility.  But why was he there, if it were indeed he?

Who had made the hole in the trunk-room wall?

It was not vandalism.  It had been done quietly, and with deliberate purpose.  If I had only known how to read the purpose of that gaping aperture what I might have saved in anxiety and mental strain!

Why had Louise left her people and come home to hide at the lodge?

There was no answer, as yet, to this, or to the next questions.

Why did both she and Doctor Walker warn us away from the house?

Who was Lucien Wallace?

What did Thomas see in the shadows the night he died?

What was the meaning of the subtle change in Gertrude?

Was Jack Bailey an accomplice or a victim in the looting of the
Traders’ Bank?

What all-powerful reason made Louise determine to marry Doctor
Walker?

The examiners were still working on the books of the Traders’ Bank, and it was probable that several weeks would elapse before everything was cleared up.  The firm of expert accountants who had examined the books some two months before testified that every bond, every piece of valuable paper, was there at that time.  It had been shortly after their examination that the president, who had been in bad health, had gone to California.  Mr. Bailey was still ill at the Knickerbocker, and in this, as in other ways, Gertrude’s conduct puzzled me.  She seemed indifferent, refused to discuss matters pertaining to the bank, and never, to my knowledge, either wrote to him or went to see him.
