Previously published in the print anthology Partners in Crime.
Tommy and Tuppence Beresford are called to duty at an international detective agency. On assignment, they are told to be wary of the number sixteen. If they see it in writing or hear it in conversation with a stranger, that means they are close to finding the spy ring they seek.

This isn't really a short story, it's just the introduction for the other shorts in Partners in Crime.
Tommy and Tuppence have been happily married for about 6 years, but Tuppence is wishing for some of the excitement they had in their lives when they were young(er) adventurers helping the government.
Serendipity strikes and in walks Mr. Carter (from the The Secret Adversary) and asks if they would once again like to help their country. A defunct detective agency owned by a now-imprisoned Theodore Blunt has been taken over by the government, and Carter would like Tommy and Tuppence to take it over and be on the lookout for spy shenanigans. A blue letter with a Russian stamp that has the number 16 under it.
The International Detective Agency is born!
If you're looking for a short story, this isn't it. There's no mystery and no real story other than to set up other short stories.
3 Stars. Light, frivolous and fun. This is the 1st short of the 17 in Partners in Crime but my review is for the first two. Christie released the book in 1929. It's one part mystery and one part the amusing interplay between a mid-to-late 20s married couple. Why two stories in the same review? The first is just the intro to the following 16, especially the second, A Pot of Tea. The two go together - as do Tommy and Tuppence Beresford. They are bored, especially Tuppence. It's an important decade for women, and she has no desire to be stuck at home. "I want things to happen. Exciting things." Her husband works for the Secret Service in the UK but at a desk job. His boss visits; the Chief, Mr. Carter, wants the them to take over the management of Theodore Blunt's International Detective Agency. Apparently Blunt had been a double agent siphoning information to the Bolsheviks (soon to be called the Soviets) in Moscow. Carter's idea is that Tommy and Tuppence may be able to draw foreign spies into the open. But little happens in the 2nd other than a lovelorn man asks for help because his young lady has disappeared. Excitement must wait. (Aug2026)
I'm logging these even though these belong to a book called Partners in Crime because I want to have read the whole collection and it's unsatisfying to leave this unadded when I have indeed read them.
Read as part of the short story collection:
- Partners in crime - Capital Christie (13/02/2026)
Tuppence is complaining about being bored and wanting something exciting to happen. It is just then that Tommy and Tuppence are recruited by Mr. Carter to pose as Theodore Blunt and his assistant of the International Detective Agency in order to catch a Russian who communicates by sending a blue envelope and a Russian stamp referencing the number 16. Not much happens in this story other than to introduce the idea of international intrigue and establishing them in the detective agency.

Tuppence is bored after six years of marriage, wants something exciting to happen. Tommy's Chief arrives with an offer to run a private detective agency with suspicious contacts under the original owner's name.
To be honest, this isn't a true short story, it is more an excerpt set-up for a longer story. The mystery is barely explained, forget about a solution. Tuppence also doesn't come off well in this snippet. 2 out of 5.
On of the Tommy and Tuppence series. Tuppence is bored at home, Tommy is mulling tgings over at work. A colleague persuades them to take a leave of absence and stand in at a Detective Agency.
It is always fun to see a different side to Agatha Christie beyond Miss Marple and Poirot
This isn’t really a short story, it’s an introduction to the other short stories. It sets the stage for Tommy and Tuppence to run the International Detective Agency.
2⭐️s because I’m not a fan of Tommy and Tuppence’s “whitty” banter about their marriage.
I have yet to read anything about Tommy and Tuppence, and now I really want to. Still this wasn't that amazing of a read as I am usually feeling from Dame Christie.
TT intro story of partners in crime collection , not much in it just the formation of blunts agency! Along with stories 2 3 and 4 becomes pink pearl on LWT in 1983 with James Warwick

Less a case unto itself than an introduction to the larger narrative that weaves these stories from Partners in Crime together, as Tommy and Tuppence take over the detective agency.
Definitely not a 100 pages long unless the publisher forgot to add the other half of the story. This short story is a preview or introduction on how Tommy & Tuppence became detectives. Not very interesting as Tuppence is wanting excitement and they think a "fairy" grants her wish.
