Bell turned it over. “Lachesis muta? Oh, yes. He’s a doozy of a snake. Dripping deadly venom and mean as a hanging judge. You know, the Cumberland Hotel is only ten blocks up Broadway. I’ll bet I can talk my way into a Pathology Society meeting with a pretty girl on my arm, if you want to go see him.”

Marion shuddered.

When the champagne arrived, Bell raised his glass to her. “I’m afraid I can’t say it better than Mr. Rector. Thank you for making me the most fortunate gent on the Great White Way.”

“Oh, Isaac, it’s so good to see you.”

They sipped the Mumm and discussed the menu. Marion ordered Egyptian quail, declaring she had never heard of such a bird, and Bell ordered a lobster. They would start with oysters, “Lynnhavens from Maryland,” their waiter assured them, “big ones sent up special for Mr. Diamond Jim Brady. If I may recommend, Mr. Bell, Mr. Brady usually follows his lobsters with some ducks and a steak.”

Bell demurred.

Marion took his hand across the table. “Tell me about your work. Will it keep you in New York?”

“We’ve landed a spy case,” Bell answered in a low voice no one else could hear over the stir of laughter and music. “It’s tangled up in the international dreadnought race.”

Marion, accustomed to him revealing case details to her to hone his own thoughts, replied in the same level tone. “Rather different than bank robbers.”

“I told Joe Van Dorn: international or not, if they kill people they are first and foremost murderers. At any rate, Joe will fort up in Washington, and he’s given me the New York office and carte blanche to dispatch operatives around the country.”

“I presume it has to do with the naval gun designer whose piano blew up.”

“It’s looking more and more that it was not a suicide but a diabolical murder deliberately staged to appear to be suicide. And in such a bizarre way as to discredit the poor man and the entire gun system he developed. Of course, the hint of bribery taints everything he touched.”

Bell told her his doubts about Langner’s suicide note, and his conviction that the Washington Navy Yard prowler seen by old John Eddison had indeed been Japanese. He told her how the deaths of the armor expert and the fire-control expert had been originally presumed to be accidents.

Marion asked, “Did anyone see a Japanese man in the Bethlehem Iron Works?”

“The men I sent out there report that someone was seen running off. But he was a big fellow. Over six feet. Pale. Fair-haired. And thought to be German.”

“Why German?”

“Apparently as he ran for it he was heard to mutter, ‘Gott im Himmel!’”

Marion cocked an exquisitely skeptical eyebrow.

“I know,” said Bell. “It’s thin stuff.”
