“Yes, sir.”

“Thank you, Bill.  The expense will be trifling.  Collect it from the cashier in the morning, and tell him to charge it to my account.”  And Cappy hung up.

At once Mr. Skinner took up the thread of the interrupted conference, and it was not until three o’clock that Bill Peck left his house and proceeded downtown to locate Cappy Rick’s blue vase.

He proceeded to the block in Sutter Street between Stockton and Powell Streets, and although he walked patiently up one side of the street and down the other, not a single vase of any description showed in any shop window, nor could he find a single shop where such a vase as Cappy had described might, perchance, be displayed for sale.

“I think the old boy has erred in the co-ordinates of the target,” Bill Peck concluded, “or else I misunderstood him.  I’ll telephone his house and ask him to repeat them.”

He did, but nobody was at home except a Swedish maid, and all she knew was that Mr. Ricks was out and the hour of his return was unknown.  So Mr. Peck went back to Sutter Street and scoured once more every shop window in the block.  Then he scouted two blocks above Powell and two blocks below Stockton.  Still the blue vase remained invisible.

So he transferred his search to a corresponding area on Bush Street, and when that failed, he went painstakingly over four blocks of Post Street.  He was still without results when he moved one block further west and one further south and discovered the blue vase in a huge plate-glass window of a shop on Geary Street near Grant Avenue.  He surveyed it critically and was convinced that it was the object he sought.

He tried the door, but it was locked, as he had anticipated it would be.  So he kicked the door and raised an infernal racket, hoping against hope that the noise might bring a watchman from the rear of the building.  In vain.  He backed out to the edge of the sidewalk and read the sign over the door: 

    B. Cohen’s Art Shop

This was a start, so Mr. Peck limped over to the Palace Hotel and procured a telephone directory.  By actual count there were nineteen B. Cohens scattered throughout the city, so before commencing to call the nineteen, Bill Peck borrowed the city directory from the hotel clerk and scanned it for the particular B. Cohen who owned the art shop.  His search availed him nothing.  B. Cohen was listed as an art dealer at the address where the blue vase reposed in the show window.  That was all.

“I suppose he’s a commuter,” Mr. Peck concluded, and at once proceeded to procure directories of the adjacent cities of Berkeley, Oakland and Alameda.  They were not available, so in despair he changed a dollar into five cent pieces, sought a telephone booth and commenced calling up all the B. Cohens in San Francisco.  Of the nineteen, four did not answer, three were temporarily disconnected, six replied in Yiddish, five were not the B. Cohen he sought, and one swore he was Irish and that his name was spelled Cohan and pronounced with an accent on both syllables.
