Statuesque: nine women, from 172 cm to 178 cm

Violetta is thirty, slender, black haired, and the tallest person in almost any room she enters. History and Victorian engineering out of hours; three hours at £700 for the arcade, the river wall and a table, or £900 across four.

Stacy is twenty two, slim, near black brown, and climbs things other people have talked her out of. The tower and supper afterwards take £700 over three hours, and £500 is plenty for two when you are staying near the Olympic Park in Stratford.

Milena is twenty five, curvy, black haired, and 175 cm of calm that nothing shifts; a curtain and a table want four hours at £900. Karolina is twenty seven, slim, black haired, and will check the high water time before she picks a side of the table; three hours at £700 is the shortest that does not feel clipped.

Samanta is twenty seven, slim, dark brown, orders rare, sits with her back to the wall and misses nothing. Dinner is her format: £900 across four hours, or £700 across three when the table is at eight and the evening ends at eleven.

Michelle is twenty seven and curvy, dark brown hair worn long and straight, and she takes the seat facing the room and makes everyone else relax. A full table and a dockside walk come to two hours at £500, and £900 across four is better when other people are joining you.

Vanessa is twenty five, slim, sandy brown with balayage and hazel eyes, and she counts the approach lights on the dock for fun. An evening that begins after a flight works well inside £500 over two hours; make it £700 over three when you want the quay and a table as well. She covers the E16 hotels.

Angelika is twenty four, athletic, black haired, and swims with a squad at six in the morning; a table and the dock walk fit inside two hours at £500. Patricia is twenty eight, slim, auburn brown, and carries four hundred years of river history and a dry way of telling it. The pub, the walk and a table with no clock watching come to £700 across three hours.

Both work Canary Wharf as their home ground, and Patricia adds the Wapping stretch of the river to it.

Four of the nine are also in raven haired, four in brunettes and one in auburn. By frame, six stand in slim and slender and two in curvaceous, with Angelika the ninth. By age, Stacy and Angelika are the only two in early twenties and Violetta the only one in thirties.

If the evening is a client table rather than a dinner, the brief matters more than the height, and the format for it is set out on after hours. Every booking runs through booking.
