Shipunov and Ivanchikov
also: Шипунов и Иванчиков, Shipunov and Ivanchikov
The named parties in the bankruptcy case (конкурс) Kvashin claims kept him working day and night away from his flat -- the invented-sounding excuse he leans on twice to explain his five-day absence. Never appear on stage.
Reading notes
- Bad Weather §41 the Shipunov and Ivanchikov bankruptcy case
"Конкурс" here denotes a bankruptcy proceeding (insolvency administration), an area of a barrister's practice that could plausibly involve long hours away from home -- the specific, official-sounding detail is exactly the kind of texture a fluent liar like Kvashin supplies to make an alibi convincing.
